Then either the charging system is not up to snuff or the PTO is pulling too many amps I use a clamp meter to check current draw A good PTO should draw around 3 to 5 Amps depending upon which model it is Some have air gap adjusters so check yours The bigger the gap the further the solenoid has...

You are right about the surface of the jets which is why jets are sized with end mills or 4 flute jet drills to give a smooth bore. However the blue pack are tip cleaners which are files and should never be used for jet cleaning as you can easily make a round hole into an oval or funnel the ends...

No body jumped to any conclusions . That is exactly why he was asked in the first response " how old is your grandson" However the reply was basically " None of your business" From which one could easily jump to the conclusion he was trying to hide the fact the grandson was a small child who...

No Drop Shipping is a process used by a lot of bulky goods retailers where they have the floor stock to show you the item and when you buy one they order it from the factory after you pay them and the item is then shipped directly from the factory to you so they never see it. Share trading...

Fair Trading did over a scammer last year that claimed they could get anything . If they could get it then fine but if they could not then,,, You paid and they shipped an empty carton with a label printed using heat sensitive ink that faded away in a couple of days on labels where the glue dried...

MY 2 stroke 160cc Victas rip through tall grass far faster than a modern 190cc B & S or Honda on any brand of bowl. And this applies to the 2 blade rear discharge , 2 blade side discharge and even the 4 blade mulchers although the latter tends to plug up the deck when cutting more then 6". Bear...

And I thought it was only me who could not get these mongrel things to work properly

Usually the float valve does not shut off the fuel which leaks out & fills up the crankcase When the owner pulls the starter oil spews out everywhere . So start with checking the oil level then tossing it out Remove the fuel tank & clean it out Slide the carb off over a container of some sort...

Did you replace the fuel lines onto the correct spiggots on the carb The one closest to the bulb is the return and the one furthest away is the supply. I have a golden rule for cube carbs If they are opened up then both diaphragm & gaskets get replaced If the metering valve needle has to come...

Go to Oregon's web site and drop in your mowers model numbers. That should bring up whatever blades Oregon makes for your mower along with the complete dimensions including the hole diameter , OR Drop your model number into Exmarks web page then note the blade numbers Being a commercial mower...

Mice can swim A big carpet snake, say 12' will eat 4 mice once a week. IT was forseeable West of the hill has been in drought for 4 to 11 years depending upon the actual place. Thus nearly all of the natural preditors were in short supply. Then we had the bushfires which killed around 1/3 of all...

It is healthy for people to express opinions just so long as it does not become violent. Suppression leads to resentment & anger, some thing that most forums administrators fail to understand. I for one have no political affiliations & vote each year on the platform presented regardless of which...

You also have to see this in the contex of the B & S Bankruptcy. Almost no OEM factory specified B & S engines for this years production because B & S was bankrupt & could not guarantee supply Kohler are already fully booked as obviously is Kawakasi So either they just have to wait for local...

It is a problem when you have voluntary voting so the parties have to whip up their followers into frenzied belief in order to get them off their bums & down to the polling booth. Thus you end up with 3 factions in the population two who believe more strongly than the most artent religios...

Most trimmers come with a simple shoulder strap. Customers never read the instruction and if they do never adjust the clip on the shat so without any hands on the trimmer the head sits about 1" above the ground Slightly better are the professional H type of harnesses. These are a bit more...

Listen to your trimmer carefully If it is stopping lean then it will have a harsh sharp exhaust note so you know it is not getting enough fuel. If it is flooding out it will blow some smoke and start 8 stroking before stopping. If it has partially blocked exhaust then it will sound just the...

My go to is plastic fold down ski boat seats A lot more comfortable than most mower seats, waterproof & more weather resistant. Down side is you have to cut the base to fit a seat switch I usually mount the seat to the old adjuster plate then fit a switch under the plate rather than inside the...

Vertical engines by the nature of their shape have sumps that are very shallow with a large surface area. Thus on a quite moderate slope the oil level on one side of the engine can drop down to 1/3 the usual height. If the engine has an oil level sensor this will be low enough to cause the oil...

Yes but it sounded so good on the podium "I will bring American jobs back to America " And President Trump was not alone his predecessor did the same thing with the "Working America" scheme. Really got under the skin of countries down this way who had put in infractructure to support...

EFL is the effective length of the belt It is the system used in the EU so they can be different to the USA ( outside length ) & old Commonwealth countries ( inside length ) And yes they are inches So in most cases you would fit a US 100" belt if the pulleys are all in good condition or a 99"...

Batteru voltages, before starting, while running and running with the PTO engaged will tell the story.

Started with the previous administration having a trade war with China so China stopped supplying assemblies to USA factories. So lots of stuff that is made locally could not be made because the company that used to make the cords for Milwaukee for instance closed down Now Milwaukee can not make...

World wide shortage of Kawakasi parts and engines

Based on those numbers your battery is gone If you continue to use it you will do damage to the starter motor and probably the alternator as well so start with a new battery . All solenoids ( the pto clutch is just a solenoid ) have a fairly specific cut off voltage after which they just shut...

Got a riding buddy at Dubbo who uses a modified drain cleaning vacuum to clear them out of his winter feed silos I think he said it is 5,000 gallons and he fills it between 2 & 5 times a night . All of the feed that was not eaten is contaminated beyond use . And yes, 2 to 6 pups event 14 days...

GEt a good pressure gauge that reads 0-20 PSI at full scale Start with 15 and go down 1 psi at a time till you find a pressure that is right for you. And remember on a hot day it will be higher & on a cold day it will be lower Low in the morning & high in the afternoon . When you find what...

Bad rings will foul the spark plug & produce enough smoke to rid the surrounding 5 mile area of mosquitoes . You need to start eliminating things one at a time 1) electrical fault in ignition Remove the kill wires from both coils Problem goes away = bad safety switch, ignition switch or short...

You will need more rats than there are on Capitol Hill for that and rats don't pee all that much . OTOH we got about 200,000,000,000 excess mice right now if you want some .

But it is not a foam only filter he is talking about It is a paper filter with a foam wrap They get fitted dry

Double ditto on what Star said THe postage on the precut lengths will be more than the price of having a mower shop cut you some off a roll. And further to that it will be genuine Tygon and not "fuel line in popular yellow colour "

Yuck Worst one I ever had the nesting material was mostly cloth which was getting jambed between the starter pinion & the flywheel teeth locking the starter The owner had burned out the starter motor after burning up a battery before he called me in .

You have it connected wrong The throttle cabe can not be connected directly to the throttle butterfly because that prevents the governor moving the butterfly without moving the throttle cable which it is not strong enough to do .

As they say in the science fiction movies,,,,,, You are not alone Thanks for the update

Take a deeo breath & give us the full story What was it running like before and when was "before " What engine does it have fitted

The pre filte is just that. A prefilter It is not meant to stop sub micron particulates , It is there to stops sticks stones & grass clippings that if damp can cause the paper to rot through The paper is doing the filtering , the foam is screening General rule is you only oil the foam on foam...

When you turn the ignition on the pin should fully retract Off the mower a 9V transistor battery is enough to make it retract

Charles, With all due respect & not trying to be agressive . We are here to help people with their lawn equipment to make their lives easier Not to assist people injuring themselves or others . IF you want assistance then please just answer the questions. As a rule no one here will tell any one...

The power to the purple wire is a daisy chain from the battery to the B terminal on the switch to the S terminal on the key switch to the pto switch to the brake switch to the solenoid. Something in that loop is not passing the current through.

Either it was too loose to start with or the bearing is seizing and unscrewing it . Check the pulley carefully

Fish, HE put it in his signature 331877 1371-B1. Larry, If that engine has a carb solenoid then check it is retracting fully when energised

Not sure is it is deliberate but all of the latter models have had rough machined heads. Triumph did this on the tripples at one time to stop the head gasket extruding out the sides , again the sealing surface was too thin, so I thought the rough finish was deliberate. Weather it is on not it...

Just keep a head gasket on the shelf is good enough. The intek range was a copy of the Japanese designed Vanguard range and when it was done they make a dogs breakfast of it. Too little metal on the bridge , too thin a head at that position & not enough clamping force. The bolts nearest to the...

Got to outdoorpowerinfo And look up the repair index for some nice photo instructions on who to clean your carb

YEs, just make sure you mount the box some where that the cooling breeze blows over it .

Not fond of rat & mouse baits. They often end up in the belly of whatever usually eats rats & mice so kills off their natural preditors thus makes the problem worse. OK for inner city blocks where few owls, eagles snakes etc live but a dissaster in outer urban / semi rural blocks .

Please start a new thread for the trimmer or things just get confusing

That narrows it down to about 25 different engine models. If you want us to help you there are two options 1) buy some beer & steaks then ask us round for a BBQ 2) provide the full details we ask for. The site gets about 200 posts a day at this time of the year and those who make it hard for us...

Check the battery voltage engine off , engine on & engine on with PTO on . off should be around 12,5V , on should get to around 13 V after a minute of two , PTO on should be a little lower but higher than the off voltage.

This is where a little bit of Sherlock Holmes enters mower repair. You have a look at where the mower lives. Had a customer who kept their mower in the same shed as the chicken food , horse food & bedding hay Every time I came the mower was stuffed with mice Solution was to park it outside in...

Try mowing with the fuel cap loose. Check the valve lash again, it it is out again you could have a loose guide. I assume you have pulled the carb off & cleaned it out properly ? although I did not see you mention this . Crud builds up in carb solenoids preventing them fully retracting and...

Waste of time contacting MTD unless you want to buy a complete new tranny. They do not service the hydro units nor supply any parts for them . You need to look up the IPL for your transmission on the hydro gear web page There should be a short lever to activate the bypass which may have fallen off .

You can fit a points eliminator to any engine That is the stand alone module that is wired into where the points used to go . Instructions are in the unit .

Both plugs showing a lean burn would indicate a common carb problem Leaking gasket or float level too low .

Might be a regional think Link went strait to the google sign i page demmanding I open a google account which as explained I have no intention of doing. IF I want free help then the onus is on me to make things as easy for those who will help me as possible .

One of the nice features of this forum is it allows videos to be embedded . If you expect people to create a google account in order to watch a video to help a person they do not know then you have just arrived at "a bridge too far" The very most I would be willing to do is look at an open...

Undo the deck to remove it from the mower Lift the rear of the mower ( because it is the light end ) and move it around to leave the deck exposed Drive away if you want . With the mower out of the way, pry bars or similar should be able to get the deck off the root. If not then undo the nut on...

Yep there is only so much you can keep in a bone yard. I got about 50 deceased ride on mowers when I bought the repair run 8 years ago and in those 8 years I have sold 4 gearboxes to racers and one deck gauge wheel. It has cost me more in time looking for used parts that might fit than it would...

That is the sort of stuff that usually ends up on ebay & amazon. defective carbs that have failed B & S quality control

You get them from a mower shop that sells after market parts from companies who stock parts that are guaranteed like Oregon , Prime Line , Stens & Rotary

Never ever run a hydro at anything other than full engine speed, unless you want to buy a new mower every year run the engine at full speed then push both lap bars forward till the mower starts to move at the speed that you consider safe The big problem with ZTR's is there is almost no weight on...

To work, the throttle has to pull on the governor spring and nothing else. It is the balance between the tension in the governor spring and the pressure from the governor that works against that spring that actually controls the engine speed. The throttle cable simply controls the tension in the...

Cyclons charge at a similar rate to standard open cell lead acid batteries. However being a spiral cell battery they have an astronomical discharge rate and are extremely mechanically strong. The problem is going to be getting enough CCA to turn over the engine from any other type of battery...

Yep, Been buying a lot of B &S parts through the local JD dealer lately Cheaper than from an authorised B & S distributor and they always have the parts in stock Where as the JD warehouse rarely has any parts that I need . Down side is having to work out the JD part number

IT is the seat switch Some of them have anti tamper plugs that short out if the plug is not tight The plastic tabs break off then the actual switch bit twists so the plunger no longer activates the switch The actual switches rarely fail themselves cause they are out of the weather.

This is the Nikki copy off Alibaba Nikki copy Postage to the USA should be about $ 20 for up to 3 If you don't like that then troll through this 20 pages of Ruixing carbs for B & S engines Unlike Evilpay Alibaba actually vets all of the retailers so these are generally all perfect carbs, not...

Not much to see Most are just a chip about the size of a micro SD card The circuitry is all over the web if you are curious, just search for Hall effect trigger circuits Very simple . Any 1/2 decient repair workshop ( not a big glass front showroom ) should be able to test them for you, about...

Did you put a kit through the carb ? If so then which kit ? The WYA series is a rotary valve type carb and if the engine runs up to 3/5 throttle then either the carb filter &/or main jet are clogged causing it to die lean Or the metering needle is set to high causing it to flood out at higher...

This is one of the rare occasions I would suggest checking Amazon or ebay There are some Ruxing parts available I can get some from my wholesalers here and some more from agents in Hong Kong but mostly for cube carbs. The whole idea of using Ruxing is they only supply to the OEM company under...

Then what about Kirchoff ? Lots more fun with him cause you get to play with your pocket calculator and numbers 10 digits long .

Ruxing do not have any presence anywhere outside China Thus you can only get them through the OEM Dealer network. Briggs just shafted their suppliers, workers & the government to the tune of $ 600,000,000 . And this is the second time they have done this Thus suppliers that still willing to...

For a diy guy remove spark plug and place a SMALL SHORT shot of carb cleaner down the plug hole Put in a clean fresh plug, or a hot plug strait from a mower that has just been run Pull the handle Engine goes bang = ignition timing is good Engine does not go bang = pull blower housing and check...

Usually people who understand electricity would write 2kΩ to 3kΩ or at the most precise 2.0kΩ People who don't understand write the numbers they see like 2137.52 Ω

I seriously doubt that the diagram is wrong What does happen is people hook the control rods to the wrong butterflys This is very common . Remove your control cables then move the high idle screw and see which arm moves That arm is the one which should be connected to the governor arm via a...

resistance numbers are there to occupy the minds of the brain dead who have no idea how a modern hall effect triggered coil works. But they have an expensive meter that flashes a lot of numbers so it must be important to their tiny minds. There is a good reason why you do not see resistance...

A line trimer & chain saw fuel system is a closed loop pressurised system. They have to be so that the tool will run upside down Very similar to outboard motors on boats. The fuel pump in reality is a pressure pump that pumps up the tank to around 5 psi to 10 psi Some where in the system there...

You want to expand on what "bumps into gear means " Difficult gear shifting on a manual box is generally the clutch failing to take drive pressure off the box or broken shit keys inside the box

Give Randys a ring HE is good at finding obsolete parts or knowing what other bits will fit .

Yeh OK it is a bit bigger than a double garage & car port . The smallest block you can build a stand alone house on down here is 0.1 acres and even a modest house on a block that size has a front yard so small to make putting a lawn in look like the space between wheel ruts and usually on blocks...

No problem for a good old mower with a manual gearbox & manual PTO Those hydros & electric clutches gobble up a massive amount of power LAziness / convienance cost money . I mow regularly with a 3 speed 8-36 There was a 40 " deck available for this mower when new .

Slomo beat me to it Why do people seem afraid to go to the manufacturers web page & download the IPL's & manuals ? It is not rocket science So before you do the brain dead "ask google" who will show you all the sites they are paid to show you, try Briggs & Stratton . Next the big question is...

So this is where some one starts to send PMs and organizes to post some over the border

Batteries are what tanked electric car development and are what has choked it ever since. You just can not get the energy density needed to power a car over a useful distance. So it was fine in the 1900's when the rich ( you had to be rich to own an electric car ) were using cars to replace...

Does not make sense to have a switch with B+L+S & M+G at the same time unless the mower uses a NC relay on the magneto kill wire. M+G+L uses the alternator as a brake to stop the engine faster . As you have worked out by now there are a lot of variations and the number of terminals alone is...

Pull the float bowl off & check for water If there is water there , check the fuel tank by draining some fuel into a glass jar . Check the fuel can you used to fill the mower with .

From what you have just posted then you either have the wrong coils, defective coils or the wrong flywheel or defective flywheel or have been installing the coils upside down. Or a combination of any or all of the above. Downside of using similar castings and flywheels with the same tapper on...

HAd a Dillion set since 1972 when he came into the scrap yard, cut a steel beer can and an aluminium beer can in 1/2 then welded them together. Cut a comb from a lump of 2" thick armour plate. I can weld rust with it now. Dillion kits do not need special rods & no flux for anything other than...

Ultimately it is the cheapness of the purchaser People will not pay a reasonable price for just about anything now days and the shop with a mower that is 50¢ cheaper will get 500 more sales. Thus the cost cutting has to be done somewhere. A self tapper is a very quick one man job and requires 4...

When you were young there was this funny stuff called petrol that you bought from the pump Now you get "fuel" which is not petrol but a light fuel oil mixed with whatever scrap by-product solvent the fuel companies can get cheaply

The metal is very thin and the rust does not make it any easier. I torch weld them in situ Doubt you could do that with an arc

Walker being a family owned company are very proud of their products and have a service help desk second to none. So give them a ring. If it is a known problem thy will tell you how to fix it. Otherwise it will either be a wire making contact where it should not or a carb problem, like water in...

Hammer you just made my day Also learned some thing because I always thought Kettering was an Irish man ( I will of course check )

No that is another switch but they are visually the same There will be one on each stick

Cube carbs are basically all the same internally Only 3 types The big difference is the size of the venturi ( hole ) . after that is is nothing more than how it hooks up The good thing is most of the control shafts are the same diameter & only held in with an E clip. Most of the butterflys are...

Plastic welding is about as simple as you can get The only real requirement is the parts HAVE TO BE CLEAN Traditional metal welding melts the filling material into the parent material which is partially melted. Plastic welding melts nothing and if you are melting then the tool is way too hot...

If you have a big slope then look for a good second hand 2 stroke mower or cut the grass with a line trimmer. If it was my yard then I would put in a garden & forget about mowing all together. Think about a flowering ground cover then pop a couple of shrubs in after you have been there for a...

Also check the tank vent ( usually in the cap ) Generally they leak so don't hold pressure but they can block, cause the tank to over pressurise . At around 15 psi the metering valve opens ( called pop off pressure ) and that causes the engine to flood But usually it will be either crud holding...

sounds very much like a blown head gasket

How much water is totally dependent upon what the humidity is on the days when the compressor is running Nothing stopping you from putting a different cock in the hole for the current drain cock and running some tube to a drain outside IF you use it a lot then run the tube to some mint that will...

Every one who repairs small engines and every mechanic trained since 1901 knows how a Kettering ignition works. Every one who was not asleep during their science classes would know how coil works . Glad you got it fixed. For future reference when you have fuel compression & spark but no bangs...

Thanks Will I have 2 of the JD Built Hondas (HA4120's) in my service run Their ID tag actually says "built for Honda by JD " so not so secret. One customer died a couple of months back so I expect that mower will be gone Also got 2 rebadged Yanmars 435's but they are really sub compact tractors...

Yes it has but it is a little different It is called a metering valve and is moved by the metering diaphragm. Both Walbro & Zama have detailed instructions about how the various carbs work & Walbro actually have some videos

Down here I think it was a $ 600 upgrade which included the steel blower housing and the filter . Not real popular because the FX engine is only $ 800 more . Only know it because had a customer ask me how much to do it as comparred to having the dealer do it. I ended up putting on an EngineAire...

Can't say I have come across the ones you are talking about. The only ones I have dealt with are the 1/4" thick pads that press on a plate on the top of the pulley or the 1/4" thick ones on the tension arm with a slave brake hooked up to it that press on the edge of the pulleys. Probably too new...

On the mower end of the lever when in the park position they will be depressing a plunger on a switch. Some can be very hard to find hidden inside frame channels out of the way . Find the switch MAke sure the plungers are depressed and the plug on the back is secure. Remove the plug, spray you...

Thanks for the feed back Always good to close a thread properly Even better when it is a success

Cube carbs have very fine passageways that can get blocked by evaporated fuel deposits & corrosion Some have rubber tipped check valves that perish & stick closed As such buying an old used one is just as big a gamble as buying an unbranded carb from a scrap metal merchant on the web. Some carbs...

IT will be electro etched into the crankcase If you go to the Toro web page and enter your mower model number (74621) in the manuals section it will bring up the engine service manual for that mower as well as the parts book, owners manual mower manual and the quality of cut manual. Broken...

It could actually be out of time. Have you pulled off the flywheel & checked the ignition timing key ? Have you verified the valve timing ? not unheard of for the hand held GX engines jumping a tooth on the timing belt

We are all here to learn I learn stuff I did not know every day The day I stop learning is the day they shovel dirt on my face On the web we are just electrons exciting a screen. Nothing should be taken as gospel truth unless verified by the reader. Thus no signature line in my posts with...

Will you stop this please Slomo it is getting embarrassing . Back when I first came here most of the replies were in the vein of turn bolt B 3 times to the left and put locktite on nut 5 While this is exactly what needed to be done it did not tell the poster why they were doing it which in the...

Wrong way round Springs get weaker over time not stronger. ORiginally the spring was soft wire you could bend between your fingers. After being wound on the mandrel it is heat treated to make it springy Over time the heat treatment wears off To do it with heat you need to cook the spring at 400C...

IT is nothing more than excessive fuel in the muffler. Mufflers now run red hot to burn off any fuel not burned inside the cylinder When you turn the engine off fuel is still drawn into the engine & expelled into the muffler When the concentration of fuel to air is correct for igniting at...

Only needs to be 1/4" thick for a spindle brake Now that I am thinking, you could just grab the cheapest car disc brake pad an cut the whole thing in 1/2 the bolt the entire pad to the mower You could probably get away with a block of hardwood now I think of it HArdwood is what used to be used...

IT uses a different top plate with a track for the counter weight guide In your circumstances I would take the case & top cover to a welder It can be TIGed from the outside if you clean the case really well & the top plate needs to be there to clamp it nice & tight to prevent warping Gas...

FWIW :- When I bought the service run I inherited a couple of lengths of tractor external brake band material I have been cutting lumps off of it for 8 years to repair blade brake pads Works a treat Other than that any shop that relines clutch & brake shoes should be able to replace the...

Big business was happy to sell it's sole to China for the sake of a hand full of gold for the management & shareholders. Now they are paying the true price. Downside is unmet demand will allow price hikes so the end consumer pays the actual price. If you believe in Capital Market Theory this...

Not sure if there was 2 or 3 variations in the counter balance systems Nothing you can do with that block other than getting the crank & counterbalance that fits it OR get your old block welded Lots of people get away with nothing more than some aluminium putty or resi-weld . If the crack is...

And it could simply be crud in the fuel tank blocking off the outlet NExt time it happens pull the filler cap off pul the fuel line off at th filter then blow back through the fuel line There should be almost no resistance. If it is very hard then the fuel lines or the fuel tank is obstructed ...

pull the breather off the back of the air filter box and check for excessive fume If it was cranked while being excessively over full of oil could very well have done a ring in Does the compression feel a bit on the low side ? From memory there is no breather valve in the rocker cover just a...

Some one with dealer access to the Power Portal might do better but the civilian version recognizes the numbers then comes back with "no information available "

Actually the diagnosis fits the symptoms quite well . What we need to know is the actual engine numbers Being in a hopper It is most likely a horizontal shaft engine and probably a flat twin but we really need to know more to go any further .

All depends upon the load on the blade pulley There is only so much torque a 1/2" belt can handle before it lets go Mostly 5/8 belts got used on 2 belt systems where there is a single belt driving a double pulley directly from the engine then a 1/2" belt driving the actual blade pulleys There...

Sounds like the starter pinion ( gear ) is not engaging with the flywheel Take the blower housing off so you can see what is happening when you turn the key The gears are a service replacement item

If you can rotate the engine by hand Get a pair of jumper leads . Hook one to the battery - then to a good ground on the mower, I like to use the oil drain plug Turn the key Engine cranks = bad ground connection Engine does not crank then put the other lead on the power wire on the starter then...

Check the oil level Probably will be high. Float is sticking in the carburettor allowing neat fuel to drip into the engine It will get worse and can destroy the engine

I think you will find it is very much illegal to do that. back when I were a lad we use to paint the bottom of the pailings & the fence posts with old engine oil. The fences around our place were better than 100 years old as great grand dad painted them with creosote when they were originally...

Agree withy your sentiment, but plugs do go bad, and modern plugs do it more often than old plugs. Because we now have very sensitive chemical test gear we can detect the most minute amount of things like lead in exhausts. Now as we all know lead was invented by Satan and any one who even looks...

Inside lengths A section 2" less then outside B section 3" less than outside So the belts are not the same effective lengths. The pulleys will tell you which width belt to use Very few Craftsman mowers used a 5/8" deck belt.

Foam will fall apart without an abrasion resistant front piece A lump of tyre tread that a truck has shed on the interstate is about perfect

They build their own ride ons Some of the sub compacts are rebadged Yanmars in some sort of recriprocal arangement. Murray used to make the push mowers and some Sabres

oil shear is a funny subject People invisage these :long chain: molecules as being like a hand full of straw passing through a set of gears & getting chopped up. Firstly a very loooong molecule might be a couple of nanno meters The space between gears is around 1000 times bigger than the length...

Simple check is to slip the carb off leaving the fuel lines inplace , turn it sideways and blow air through the carb. If fuel sprays out the engine end then the carb is working If no fuel the carb is clogged. Now for the crunch some of the carbs have check valves and if left with fuel in them...

A Ford Vs Chey situation really I tend to use Champions in 2 strokes and NGK's in 4 strokes This is because Champions have a much broader working range than NGK's so suit the variations in blue smokes better. I like NGK's on mowers because I can usually fine tune the plugs to the engine as their...

Looks pretty self evident to me You did not post the numbers so I could go to the Exmark site and check you actual IPL but a quickie with Jacks revealed this Drive belt & pulleys Looks pretty standard ZTR to me Only trick is this view is a 3rd angle plan view so is from the top ( that of course...

First, the Prme Line kit will be fine, provided that it is the right one for your saw. Second did you test the crankcase seals ? Buggered seals manifest themselves as starting problems . Third , did you pull the muffler & check for bore damage ? The most common reason for an almost new looking...

IT costs a small fortune to make a good technical manual , excellent ones are even more expensive. Archiving them so they are available 30 years latter is even more expensive. Some one has to pay for it. Thus cheap skate manufacturers like MTD & AYP do not even make one & just send dealers the...

Really ? Some time Slomo I do wonder about you. This can only happen if there is a dead short in either the solenoid or the starter motor, in which case you will get a monumental spark when the leads are connected. And funny enough that usually causes people to pull back rather than push on and...

Rubbish Car battery , truck battery, jump start pack, 1000 pen light batteries. All the same and none will do anything to your charging system unless you connect them backwards in which case you usually blow the fuse in which case the charging system is isolated. An URBAN MYTH perpetrated by...

After you put the meter in the drawer, lock it to prevent temptation. If you want to know if a spark is being generated, a red in line spark tester is the best way to go. Rust make absolutely no difference unless it is so thick that the laminations actually touch the magnets , or the laminations...

Even if their is a smaller pulley there is a finite diameter that the belt can turn around without slipping. So you are better off putting a larger pulley on the gearbox than a smaller pulley on the engine. A slightly longer belt will slip a bit so go a little slower but of course you will go...

Before you put the key in , take a fine file to the edges of the key slot Usually a sheared key will raise a little burr that will prevent the taper locking so the next time you try & start it the key will shear again. It is also prudent to do the same with the flywheel. Don't over do it you are...

Go to a Cub dealer and look at where the belt sits in the spindle pulleys Then look at your own pulleys You will see yours have worn and the belt now sits a lot deeper and feels looser. So while the spring will have lost a little tension, that will have no where near as much effect as worn...

BElieve it or not, at higher speed this does not happen because of actual shape of the cam which at higher speeds allows the valve to close earlier You have to take the cam out, cut the lobe off and compare it to a standard cam to appreciate how it works COmputer design is a fantastic thing And...

The new belt should be wider than the old because belts do not stretch, they wear thin because they grip on the sides Because they are thiner the belt sits deeper in the V of the pulley thus the belt feels loose so we think it has stretched longer .

You are looking for a standard 1" shaft diameter mower engine with a strait drilled & tapped PTO shaft. SES SEW Both of these sites have instructions how to replace your engine. Basically you need the same PTO diameter & length , an alternator with the same or higher output and of roughly the...

Why do people refuse to go to the manufacturers web pages ? JD have all of their IPL's on line for free access Down side is you can only print / save one page at a time . Good side is they do update it regularly.

NEw post would be good. Sounds like you were supplied the wrong belt. Most belts are supplied in bulk to the retailers who then put them in the sleeves & in some cases actually put the size label on the belt. This is low value work & often done by disabled workshops where very few actually know...

The carbs that Stens, Prime Line, Oregon & Rotary sell all should have undergone some sort of quality control at source. as such they all have a warranty BEcause these are specialist mower parts suppliers when they tell you that it fits something then it will be the right carb for that...

Came across this when checking an on line catalogue for an Auction this weekend 1920 Briggs Flyer Probably the most expensive Briggs & Stratton I will ever see. Did not know they actually made waggons . Wonder if you could hitch a deck up to it ? Wonder if I can get the IPL :devilish: :devilish:

The carburettor is mixing the fuel to the air at the same ratio So all that is happening is your 500cc engine with a compression ratio of 7:1 ends up being a 100 cc engine with a compression ratio of 4:1 The lower the compression the wider the range of air : fuel ratios that will ignite. The...

That will be an early morning special. Electric welding of steel that is at near freezing point . Causes a very abrupt border between the parent steel and the Heat Affected Zone which is brittle. I would have hoped by 2020 all production managers would have been aware of the need to preheat when...

Engine replacements are the easiest way to go . If it was a Toro branded engine then it will be a Loncin. Get one of them & it should be plug & play Any other brand will require some rewiring as they use different shaped plugs. OTOH 20 minutes of plug replacements can save hundreds of dollars...

IS the connections B+L+S+M according to the letters on the back of the switch or the actual wires in the plug ? If that was the actual switching then it is putting voltage onto the magneto and that will kill the trigger chip the very second that contact is made thus destroying it

It is all about the ticket price There is 5/8 SFA difference between the FR & FS engines and it probably cost Kawasaki more to make the 2 variations than the difference in the wholesale price. However Joe Public wants CHEAPER even if they are buying the top shelf engine on offer for a...

If it won't turn off with the key then you have the wrong switch fitted There are two things that can stop the engine 1) the M ( Magneto ) terminal gets shorted to the G ( Ground ) terminal. 2) the fuel solenoid wire ( can be a couple of different terminals ) looses battery voltage . The...

This is why we use various types of plug in spark testers. The red ones are a lot easier to see but all they tell you is a spark is being generated . The 3 point or sliding electrode type test the quality of the spark but are harder to see When I get caught out without mine , usually because I...

Pushrods bend because some thing prevents the pushrod moving, just keep this in the back of you mind. The usual reason for this is overheating which allows the valve guide to move in the head so when the pushrod pushes on the end of the valve the spring compresses as far as it can before the...

The system works by varying the tension on the front ( lower ) belt . So in your case you have either routed the belt wrongly through the clutching pulleys ( pair that move when you press the accelerator pedal ) or you have positioned the springs wrong so it is pulling the belt too tight ...

It is possible to repair anything The difference is weather it is economical to do so So unless you know a crack a jack welded & machinist the you have some metal looking for a scrap bin .

The strength of a magneto spark is directly proportional to the speed that the magnets pass the coils. Ask any one who rides magneto powered motorcycles about this So what looks like a pathetic weak spark at cranking speeds can be a blow you away spark at running speeds . That is why B & S make...

Chain is getting too hot. Check the bar is oiling properly It is a big problem with pole saws because the chain is very short

Obviously some thing is not good so please do the following and report back Grab the jumpers from your car boot and jump from the battery negative to a good ground on the engine ( drain bolt is usually a good place ) . Cranks fine = bad ground strap No difference the hook the other jumper from...

Model number would help and without them all you will get is generic information If it slows down, surges then stops it is most likely a fuel problem . If it stops like you turned it off then it is most likely electrical . Simple tests 1) the instant it stops remove the fuel filler cap and...

Blowing air through the carb is not supposed to fix anything, it is a test to see if the carb is actually atomizing fuel . As I do it regularly I can tell if the carb flow is restricted or not. And yes it is a very simple carb. They are everywhere 2nd hand because of all the old B & S engines...

If you have a compressor then get a very long air duster and use that everywhere. I have a couple that are 6' long and they are great Clean the entire mower including the drive. Water & mowers do not mix

You mean cute like Frank Zappa

Funny you should say that as it happened to the copier I used to own. The Ames roller, thick it was the fixing roller was NLA and the machine sat idle for over a year till a pin ball mechanic friend saw it and put me onto a mob who did custom roller repairs and they recoated the roller . Not as...

That is fine Caruso. If every one was as careful & considerate and in such good health as you the world would be a wonderful safe place to live in. However in any particular years I would get at least 3 mowers with electrical flex wrapped around the blade spindles cause the idiot owners was...

Funny. My suppliers measure the bar as the length from the tip of the bar to the front edge of the mounting slot. This of course will always be 1" to 2" longer than the actual cutting length but the again computers & TV's measure the screen size as the diagonal distance. The killer for me is the...

Yep. The gaskets are coded by the position of the joined holes. No joined holes = smallest bore size Joined at the side is middle bore size Joined at the top = largest bore size As Stens buy the gaskets from China probably a packaging error. And yes when I can get them I use the aluminium...

Sorry to say you have either hooked up the governor wrong, or the pin inside the engine dropped out while you were assembleing it. Happens all the time

Remove & clean the carburettor Ift that makes no difference remove & clean the fuel tank replacing the fuel line

Opps sorry must have been all that love in my eyes. Will go back & modify thread # 11

Add to that they are not sealed so water from condensation will wick down the cable & start corroding the cable in the middle so when you fit a new cable leave it in the hot sun for a day, clean the surface where it will be bolted on, use a new clean bolt then paint over with liquid electrical...

As to this point, well for decades the West has been living in a fools paradise exploiting and keeping 3rd world countries in abject poverty so we can get stuff for well below the real price. If you like to believe in conspiracies well this is a real one. Managements of very large companies who...

You are never going to do a successful weld on a forged & hardened shaft that was under too much stress from the start . No matter what rods you use a weld is still a casting and fundamentally castings are strong in compression but weak in tension and shear. So Gwhit unfortunately you have 3...

Now before we end up in a cyber love in. 1) check you are getting a spark if not remove the blower housing and disconnect the kill wire from the coil 2) get a can of carb cleaner and give the engine a short shot down the plug hole then replace the plug and pull the rope goes bang proceed to # 3...

OEM companies no longer provide the specifications for a lot of things to encourage the owners to use OEM branded replacement parts for obvious reasons . Most small engines use the same oil pump and have the same oil flows so use essentially the same oil filter. I keep 4 filters , briggs long &...

IF it came through my gate then did what you said the air test is the first thing I do which saves me pulling the carb off the tank and replacing a perfectly good diaphragm & gasket. I have assumed you fitted them correctly, diaphragm to the tank. The induction tube ( manifold if you like ) is a...

But how many times did you flip the bars out when you first drove it ? Probably find the pivot bolt is also loose and the lap bar is slightly bent Also the control rod shown in the last photo has a loose jamb nut so you will need to nip it up lest it loosen in use .

The sort of thing those 1/2 wits on face book do in their videos showing how they make $ 1,000,000 a year flipping mowers using nothing but junk they pick up for free There should be a rod linking the throttle butterfly to the governor vane and then 1 or 2 springs linking the same rod to the...

Slip the fuel tank off complete with carb Blow down the air horn with low pressure air A good way to do this is to put a dunny roll center over the air inlet then blow using an air duster held about 1" or so above the top of the cardboard. You should see atomised fuel coming out of the outlet...

Doubling up on the good advice from Rivets And because they are files you can easily make the hole oval which will really suff up the flow I use micro drill bits rolled between my fingers and not held in a pin vice in lest you end up actually drilling the brass

Masonary bits should never be used on metals unless the cutting tips are reground to saw tooth profile with the cutting edge leading. BAck in the bad old days I used to reshape old masonary drills to cut HSS & work hardening steels like digging teeth & plow blades. Down side is when the tip...

The clutch may have an adjustable air gap. consult your service / owners manual. or The battery could be running down because the alternator is not keeping up with the clutch Start the mower , engage the blades then get some one to measure battery voltage Should always be 13 V or better

Most hardwear stores or auto parts stores or engineering supply stores will have an assortment rack of small tension springs

That tab is part of the lap bar designed to prevent the lap bar moving into a drive position when the brake is on Check the pivot bolt It could have gotten damaged in transit , particularly if they used the bars as a tie down point ( some people should never be allowed to truck anything )...

Yes it is screaming Increase the display size on your computer screen So get a really big screen and reduce the resolution of the screen till everything is a size you can read easily Font size is realtive to the screen resolution. It is only absolute when the page is printed so an 10pt font on...

You have to strip the fats out of the oil first or you will end up with serious pump problems, particularly on varying stroke length piston pumps. The up side is the fats are really good feed for cows & horses . And caster oil is what you use for racing on . A few around here are trying canola...

You have some corrosion on the control arm, most likely on the air damper Remove it and see if the lever moves OK BEcause these mowers are cheap the parts are cheap and require regular lubing with dry lithium spray grease to keep them moving freely & prevent corrosion.

That will only work on grade 8 or higher bolts &/or bolts that are 5/16" or bigger in diameter as the bit will just shear the sides off the slot Muffler bolts are one of the worst for corroding solid in the block .

Then you have the wrong carb The work around is to get a small weak tension spring then drill a hole in the choke plate on top of the carb on the opposite side to the control wire ( might be one there already ) then pop the spring on there to open the choke when the cable backs off

Lap bars & parking brake are connected so you can not drive away with the brake on So one or the other switch is faulty. Some of the ZTR's use an interlock in the hour meter which is easy to determine . If the hour meter has more then 2 wires, it is an interlock switch Some use a kill relay...

Choke spring is only necessary when you have a single control wire that does both the choke & the throttle . If it has individual control wires then the spring is not required . That is why when ordering parts those code numbers from the engine & mower are important

Full synthetics are made by converting a gas, usually an ethane or methane derrivative into a liquid. However the gas has to come from somewhere Most of it is a byproduct of oil refining, but some is natural gad or coal field gas. Usually it is a case of forcing the gas to react with a solid to...

There is an engineering workshop down the road with a water jet drill $ 20 and job done in 5 minutes, all that is left is the spiral of thread of the old stud / bolt Now if I had a lazy $ 30,000 ? If we have em down here in the bannana republic they must be on every street corner in the USA ...

What kills the FR's is the poor air filter, particularly if the mower is a ZTR with a bagger on it. Have needed to fit new rings to a couple like that with bores glass smooth after a year or so. One owner insisted on making a warranty clam as FR's have a 5 year warranty down here . Cost him $...

Because there is no benefit in using an oil that is specified way above what is needed to operate the engine Again I tell you these are MOWER ENGINES and mower engines are the cheapest engines it is possible to make because Joe Public will not pay for quality engines which is why Honda abandoned...

At this point I refer you to the to automotive pioneers with the name of Henry One decided to make the best vehicles in the world , so he tested them till something failed then made that part stronger & tested again. The cars bearing his name are the halmark for quality engineering , come with a...

Thanks for getting back with the final results It is a great help for others who come along latter

Bange, What you are missing is the fact that the API ( or any other standards association ) ratings are assigned according to how the oil ranks during a series of standard tests . Almost none of these tests are actual in use engine tests. And all of them were designed to test standard refined...

EFI is really only economically viable for commercial mowing. Not too far down the track all petrol mowers will be EFI as emission standards get tighter than a carburettor can attain. Untill then stick with carbs which are owner servicable

YEs but it might be very hard to see. White smoke is actually steam, well to be precise it is dry super steam. To get an ida about volume increase, a milk carton ( about a US quart ) of water makes a 8 lane 50 yard olympic swimming pool of dry super seam by volume at atmospheric pressure. So a 5...

And Kawasaki offer the Baldwin canister filter as a dealer fitted upgrade for both the FR & FS although it is quite expensive to fit to a FR There is no difference between the FS , FR , & FX engines as far as emissions go Same bore , stroke , valves, cams, ignition modules are all the same The...

Length is not really important I fit Tecumseh pads to everything that takes a rectangular pad. Did you fit the shim that goes between the pins & the front pad ? What usually happens is the pins get rust on them so you need to pull the calliper, and polish the pins. Apply some dry lubricant like...

Why do you want to adjust it ?

It is supposed to be loose. Because there is only one pedal for both the brake & clutch, the pedal has to dissengage the drive by slackening the belt before the brake is applied

Check the spindle bearings regularly. The big problem with running an excessively short belt is too much side load causing premature bearing failure. And remember bearings are a service item like belts & blades .

Buy the best you can afford & START EASILY , it will only get harder as you get older. Buy from to profession range when you have finished using them tip the fuel out start the engine & run the tool dry Lube & clean the hedge trimmer blade when you have finished. If you use them very...

Probably done up with a rattle gun Beg, borrow or buy one to undo the bolts. Get local handyman to come & undo the bolts for you Buy your parts from another dealer and send the dealer you bought it from a photcopy every time with a note you would have bought them from him if he had listened &...

Engine rotates clockwise when looked at from above This means that the right hydro gets the direct pull from the engine. The left gets secondary pull from the right and all of the slack is between the left & the engine pulley. Because of this the belt tends to slip on the left pulley which...

That cab only be the belt not turning the pulley or the pulley loose on the blade spindle OK, perhaps the bade could be loose if it has a round hole . Very important to keep the deck clean. Very common for the deck belt to pretend it is a boy scout on camp and light a fire using friction on...

every mower that leaves my shop does so with all safety switches working, unless I can not get the required part right then . There is a reason why safety switches are called Safety Switches and it is not alliteration

If he is confident in his mechanical ability and the quality of the product and in his ability to do the predelivery set up then go ahead & buy from a big box. But having metaphorically spat in the face of the dealers do not be surprised if they return his compliment should he need warranty work...

From memory they come from DC spares in HK and are around $ 1.20 a hit so he is buying them by the box load , probably down to less than $1 a piece and flogging them for $ 6 . a piece on evilpay & probably amozone as well . Exactly why the economy of the USA is in such a bad shape . Note they...

Get a 2 way tester like the Mighty Max and get the all metal one Otherwise you are going to end up with a drawer full of tools that only do 1/2 the job and will spend more time switching between tools that fixing the machine. Joe Pace has a short series on You Tube that takes you through the...

Just about all large public companies where the founders do not still have majority shareholdings are actually run by the major shareholders who are by & large hedge funds, money management funds , superannuation & pension funds , etc. These organizations dictate to the board what returns they...

Yes but I can charge them out at $ 5.00 along with the B & S part number so convince the customer I am better value than the glass fronts . Just a shame I can't get away with a 300% mark up on expensive items .

Take a step back Bange. This is the LAWNMOWER forum not the Formula 1 forum Most mower engines specify monogrades A lot of B & S push mower engines sold down here have a warning sticker that says"Use of multigrade oil voids warranty" on the side near the dip stick tube. I think some of the EFI...

Only two engine oils for me as well Stens SAE 30 or RGS 10W 40. The 10W 40 goes in everything that requires multigrade oil like Honda walk behinds and mostly 4 stroke hand helds. I service a lot of Honda brush cutters with GX 22 to GX 35 engines and the commercial customers find the 10W 30 burns...

Well we will get to the point where telephone wires are economic to strip to recover the wire. However I rather fear they will be burned in an ammonia atmosphere to remove the plastic insulation as it is nearly impossible to strip manually. Thus creating even more pollution from burning the PVC...

That is the point Slomo, it is not price gouging. A manufacturer has to be making at least a 50% gross margin on the factory gate price or they will not stay in business for very long. With highly seasons things like mowers it needs to be 80% or higher to cover the cost of running the factory...

Cute video Shame she did not use the vacuum on the brake tester as well One problem with the fuel tank test is if the carb has a return line then the tank should hold around 7 psi before it vents some pressure off What she showed only applies to systems with a single fuel line from the tank...

I have always lived by the "Teach a man to fish philosophy ". Now a lot of this is because I was taught to read and then I was taught to question what I read, and this was before I went to school . Then an engineering / science education taught me to always look for the possible failure point...

Ferrari oil will not turn a VW Beetle into a Porche and just cost the owners a lot more money Using any oil above the makers specification will usually not make a tinkers curse of a difference to the engine and in many cases will cause a drastic loss of oil pressure because the old engine will...

Most O ring kits are neoprene rubber which is not suitable for petrol In reality they are only good for water or for putting under flanged plugs & caps to prevent them from vibrating loose . And these are the good ones. Heaven only knows what the kits from China with no indication of what they...

The only conspiracy happening is from YOU the BUYERS refusing to pay a reasonable price for quality mowers. So every season the manufacturers HAVE to find a way to make the mower CHEAPER because customers will not buy it if in their tiny cheapskate minds they believe that the mower company is...

IT made no real difference I reassemble them upside down so it is O ring inside the emulsion tube and like I said a touch of silicon spray lube . To me it seems like they are using an O ring that is too hard but I am not privy to all of the design parrameters of the carb, just one of the mugs...

Weld it again and put in a brace plate or two at right angles to direction of the crack In theory there should not be any movement between the engine & the frame , if the engine is bolted solid to the frame So check the engine mount bolts are tight I can not visualize the exact set up from the...

At 5 years you have reached the design life of throw away mowers that are destroying the environment & ruining the USA economy So either pull the engine out & fix it or go buy a another pile of precious finite amount of the planets resources and toss the old to the tip. If the mower is still in...

Baldwin and Engineaire both sell large twin element 3 stage air filters for just about every engine ever made . Mechanics who were not fully asleep during their tech classes will know that carbs are jetted to have the correct air/fuel ratio from a clean filter to a 50% blocked air filter. Thus a...

The points & condenser have been replaced with a Hall effect trigger chip which is embedded into the coil covering. You can not test the low tension side ( ground terminal to laminations ) and doing such with a lot of meters will fry the chip, thus destroy the magneto . You can measure the...

They are a very tight fit, I can not assemble them by pressing together with my hands, even with a TINY squirt of silicon spray . Have bought a replacement tube only to find it was equally hard. OTOH all that I have done have worked just fine after reassembly

Unless there is another mower with that funny sort of dish belt retainer I have done a couple as described. Don't remember the belt being squeezed all that tight , then I don't remember what I had for breakfast & some times forget to put pants on when I check the mail .

You have a hydrostatic drive so it is not necessary to remove the drive e and in fact you can not do it for all intents & purposes with the transmission in the mower . You loop the belt around the shaft between the upper & lower front pulleys then around the transmission then back into the...

YEs that is normal Engine starts on full throttle then the governor will slow it down to whatever you have set the throttle to. It is a balance between the spring tension and the force generated by the governor bobweights. Stationary the bob weights are of course fully in so exert no force at all .

If the hourmeter is also the safety switch interlock then yes they do go bad. Back test wires with the meter in place to ground. If the white wire shows ANY ground connection then the hour meter is kaput .

Look and see where in the float bowl the main jet fuel hole is.

Bad mulching or lazy mowing is what causes those problems not the actual mulching Go play golf and watch the EXPERTS IN GRASS MAINTENANCE at work . The average home owner is an absolute blithering idiot when it comes to grass Nearly all seem to think their grass should look like a deep green...

IF the fuel is dripping back out of the carb then it would normally be a float problem but as this is a tank mounted carb with an overflow bowl that can't happen. So something is causing blow back through the carb Two sources of blow back at cranking speeds 1) breather 2) valves out of...

If you hear the loud click ( I like to call it a Klunk ) then the PTO is working So you have a belt problem Probably dropped off a pulley that is under one of the covers .

All the fuel solenoid is required to do is cut off the fuel supply to the main jet so the engine starves as well as not having any spark. IT is a EPA regulation to prevent the engine pumping out unburned fuel to the atmosphere. So it is an on or off device. Originally they simply replaced the...

Not sure if that is High school physics or undergraduate physics been a very long time since that was hammered through my thick head. No one is stupid if they don't know some thing unless they refuse the opertunity to learn. This change in energy levels is the basis of spectrochemistry ...

Check the oil level Should be very low Check the crankcase for a counterweight poking through Check the upper & lower oil seals for being blown out .

HE was having a dig at me With the PTO engaged you should be able to turn the engine over by pulling on the belt If the belt slips, it is not tight enough .

The backfiring causes the key to shear Get some fine valve grinding paste and lap the flywheel taper to the flywheel, exactly the same as you would lap in a valve. Make sure you clean all of the lapping paste off the top seal before refitting the flywheel. When the taper is perfect the flywheel...

Any deck can be fitted to any mower All it takes is some welding Easier with electric PTO's than manual ones . Just depends upon your proffency If you have a manual deck, it is easiest to make some sort of cable engagement .

Electricity has no colour is is a type of energy and thus has no measurable mass ( understanding of physics changes on a daily basis ). Sparks follow the path of least resistance so actually jump from one atom / molecule to the next . As the energy passes through an atom it causes the electrons...

No it won't Use "after market mower parts " and it should come up along with Prime Line , Rotary & Oregon . Don't know who the others get to make their filters .

Stens filter Well the part number on the Stens web page brought up their filter which interchanges will all of these OEM part numbers If you are looking for aftermarket mower parts the FIRST PLACE you look is the companies who supply guaranteed quality after market parts for mowers not Amazon...

And a magneto converts rotational energy into electrical energy SO the more rotational energy you have ( ie faster speed ) the more electrical energy ( bigger spark ) you get. There is a limit to how much energy you can harvest with a given coil windings ( number of turns & thickness of the...

The first reason why they are so cheap is they are assembled in CHina The second reason is they have no warehouse in the USA for either engines nor parts sucking up profits made on whole engines so they are a parracite feeding off Honda who do have a very expensive warehouse full of parts to...

And for a lot of other customers according to the colour codes for ordering parts Hayters , Stihl , Flint ,Yard-King ,K-Gro, Scotts ,Bolens, Yamaha , Polo , Sear , Deer, Viking ,Stiga , Husqvarna ,Ingersol , Massey , JC Penny & Nauder . No idea exactly what they made for these companies but they...

Lots of cheap yard rakes available from farm supply shops that fit the back of quads & mowers .

A good reason to avoid overhung cranks on line trimers Easy way to tell, apart from price is on a full crankshaft the pull start will be behind the engine On overhung cranks ( except the Ryobi lawn hornets ) the pull start will be on the inside of the engine .

Well we are going to disagree on this point The blades are hot forged then tempered or the cheap imported ones are hot forged then case hardened When the blade strikes something it usually will both bend & twist A bend can be straitened in a press but the twist requires special jigs to return it...

The whole system relies on the strength of the spring # 27. If it is weak or anchored in the wrong holes you aint going nowhere. Next is the belts must be replaced in pairs Finally the belts must be the correct profile & exact length They are not standard B section belts . The other thing to...

No But lets make sure we are talking about the same mower That is a Bolens Suburban Tractor ST 160 model 3016 from 1982 to 1984 .

I regularly cut the heads off The bolt is not stuck in the hole, it has just overtightened I cut slots across the head, point to point with a narrow cut off wheel then give each cut a healthy whack from a cold chisel Usually the head breaks off and then you can undo the bolt with your fingers...

Apart from the ones around the engine sprocket usually not for an electric PTO as it is tight all the time Look up the IPL for your mower and check what is shown against what you have in front of you

Get the short headder pipes that bolt onto your engine Cut the headder pipes off the old muffler then weld the new ones in. I do this a bout a dozen times a year The muffler is a MOWER part & not an engine part so there are 500 different ones for each engine thus the quantity discounts do not...

SO toss that multimeter back into the tool cupboard Do as was suggested way way back in post # 5 Make up some shot jumpers ( patch cords actually ) with a male spade terminal ( Yanks seem to call the forks for some unknown reason ) so they plug into the switch sockets . One at a time bypass all...

Not without some photos Loose spindle housing, broken housing , jambed blade big lump of debris stuck in a pulley. Want another 20 or so ?

I order my Intek head gaskets by the box full. Probably have better than 10 in stock in all 3 sizes Same story for the push mowers Mind you you have to d this down here because B & S Australia can take several months to replenish their stocks & get them to you. Keep 3 cams in hand for the same...

If it stops dead like it has been turned off , then that is what is happening, it is turning off Only a couple of things that can cause this 1) faulty coil 2) faulty kill switch 3) faulty kill wiring 4) faulty high tension lead On fixed throttle machines with a flywheel brake I have found the...

Because it is in the CRANKING circuit, you know, the one that is not working when the engine is hot . One usually avoids cranking a running engine, the teeth on the starter seem to object quite violently . AFAIK the only engine with a low oil sensor that will shut down a running engine are the...

I see where you are confusing everything You are measuring the primary resistance but probing from the kill tab to the laminations . THIS CAN NOT BE DONE ON MAGNETOS WITH INBUILT TIMING CHIPS ( yes I am yelling ) Between that terminal & the coil windings is the hall effect trigger chip and the...

If there is no provision for drilling the flywheel to fit the stub shaft then you need to replace the flywheel with the appropriate Honda one. Check the crank under the flywheel, it should be metric as most of the Predator ( very appropriate name ) uses the design of Honda engines that are out...

Get a tube / can of liquid electrical tape & paint over the bolt and ground lead. Not only will it prevent it ever backing off again but it will also keep water out preventing corrosion .

After some less than satisfactory dealings with B & S Australia, I am no longer fitting any more B &S engines unless specifically asked to do so . I rather think that B & S Australia is taking orders & money then holding on to it till they have enough to put an order on B & S USA. The wait times...

Check your oil level. If it is a little low the oil sentry on the engine will prevent it cranking till all of the oil has drained back into the sump and deactivated the low oil cut out .

I go back to what was said in post # 4 Make up some short jumpers with a male spade on each end and jump the plugs according to how the switches would connect them Do this one at a time thus you have bypassed the switch(s) till the problem resolves. If this does not resolve the problem then...

No such thing There is the blade that works best with your deck on your grass in your yard and that will be different to the ones that work best for me . Get a couple of different sets and swap them every month till you find the ones that work best for you. A lot of people down here run 2...

Very few people understand the difference between a real democracy & a representative democracy which is the system of just about every western government. And remember in the original Greek democracy only the male property owners were allowed to vote. So it was government by the rich for the...

If you bought it from a big box store or multi store dealer franchise then it could be an imported mower or a mower made for export so not on the Honda USA list.

Well it is part of the crank case so it will get very hot The crank should be held tight against the bearing by the flywheel on the other side so the big end journal is clear of the end plate . If the red gasket has collapsed or it was done up way too tight then that may also have caused the...

Before you do anything, live in the house for at least a full year Take a photo of the backyard every week from the same spot around an hour after sunrise, noon & an hour before sunset to get a proper feel for the amount of sunshine. Get a diary & log the rain , wind , first frost, last frost...

They get varnish build up and become sticky. Most times you can work some carb cleaner into the plunger hole then flush the gunk out by manually pushing & pulling the plunger Test the plug, it should read battery voltage with the key in the on or start position. They are very expensive to replace .

Just about the only thing you have not swapped over is the long induction tube. They tend to get cracks on the under side from heat ( thermo set plastic ). Usually it will surge . Some are alloy which do get hot & leak big time .

Not a metric bolt dimension. Diameter x pitch x length + specials So you are looking for an 8 x ? x 18.5 LH ? will be 1mm ( fine ) 1.25 (std ) or 1.5 ( coarse )

If the mower has a solid catcher you can just cut the left side out of it. Just be careful because while it will throw long so the clippings will vanish very quickly, it will also throw high so nasties can end up going through windows , hitting bystanders etc. Down here it was common to make a...

Tap away to your hearts content Carbs are designed to fit dozens of different applications but to cut cost, holes are only tapped where necessary

The starter can not blow fuses as it is energised by the solenoid which is not fused . Sounds very much like what happens when the alternator is wired backwards to the battery .

There is a limit to how far you can lift the front of the mower , caused by the back hitting the ground. FWIW I use a yard crane. That gets the mower deck to about a 30 deg slope to the ground which is enough for me to comfortably sit under the mower. When you do this it is prudent to remove the...

Take the blower cover off & you will see a switch The ones we get here are often different to the USA ones but if it is a plunger style then run a small self tapper into the end of the plunger to make it longer If it is a micro switch, then bend the arm a little Some times the atual housing can...

Usually it will be a problem with the auto choke, closing too early

The transmission is not part of the mower from Husqvarna ( or any other makers ) point of view. It is a separate entity unto itself and as such they provide no information about transmissions. Thus you need to go to the transmission maker for service & repair information . From the makers point...

Ethanol is fine in engines that are used very regularly like your car . It is not fine for engines that are used infrequently Before ethanol was introduced carbs on things like blowers & line trimmers got clogged up because unleaded is not petrol as I explained . Now the fact that the...

Lets try this again. 20 what sort of volts and between which wires ? 13 what sort of volts and measured between what wires ? Those two numbers do not add up 13V DC can not be obtained from 20V AC using the simple electronics found on mowers. One thing that can destroy a light duty battery in a...

Adjusting them HOW ?

RGS put all of their prices up 15 % a couple of months ago & Stens prices are going up 10% down here July 1. As for OEM parts down here they are 3 to 4 times the USA prices so I doubt that they could put them up any more . But I do agree with you that the big end of town has decided to maintain...

Checked the alternator output how & where and what was it ? If the recharge current flows through the key switch, that can burn out. Wire carrying the recharge current back to the battery can also be broken
