I advise this so often I can type it in my sleep Fix the old carb before you think of buying a clone carb from ScAmazon or Evilpay If you decide to get a new carb buy it from or through a real mower parts retailler as those ones are the good ones that passed quality control . The cheap ones form...

IT makes things a lot easier if we know exactly what we are dealing with The possible problems are different if this is a walk behind or a tractor ?

Seat switch has nothing to do with it unless the mower has been watching too many you tube videos posted by idiots .

NO

OK, I ahave tried to stay out of this but too much wrong information is flying around So to start with there is nothing in the light circuit in a JD L130 that prevents the loghts working other than the key switch or the fuse NO SAFETY SWICHES IN THE CIRCUIT AT ALL see Diagram below From the...

On what ?

On what ?

Which motor & what coil ? Walker liked to fit Kohlers Kohlers have a few different ignition systems Most coils have a Hall Effect timing chip in the coil ( replaces points, remember them ? ) The chip is very sensative and if ever exposed to any battery voltage it will fry Even some cheap Ohm...

Check battery cables both ends How old is he mower where do you store it Eectrical problems never ever go away

Does the choke plate cluse fully ?

Ring terminal under one of the coil mounting bolts to a flat female at the switch Falt female on the switch to flat female on the coil kill wire some times a 1/8" wide one Wires run along the outside of the plastic shroud , should have tabs to secure them

IT is not the engine size but the deck capacity tha is the problem I cut head high grass / lantana / blackberries / privet etc etc etc after the cows have been in the paddock for 6 months with an 8Hp mower easily The 26Hp Honda just stalls IT is all about how much trash the chute can toss out ...

No lights has to be a fuse or power supply wire broken

Yes the key can be sheared and no that will not stop one side from sparking Remove both kill wires and check for spark again No spark = bad coil which needs replacement

Over heating thins down the oil so it leaks everywhere

Virtue signaling Got to do some thing with all the surplus corn Self appointed saviours of the planet have tunnel vision and none of them can understand the science

An aftermarket carb with a makers name in the side of it will usually be good an unbranded unnamed carb will usually be junk reasoning is obvious.

Nice idea for strait blades. Age old story for inventors Convincing customers it is worth the money and finding the time to make them yourselves. or Finding the money to have them made in mass then then marketing them yourself I have dozens of special tools made for repairing motorcycles that...

FWIW I sand blast the blades to remove the build up of dirt & clippings How I sharpen depnds upon the mower that the blades are going onto Mowers with good overlap just get the edge touched up& nicks removed Blade with little to no overlap are different as a tiny amount of rounding to the outer...

Deck belts are a wear item and there is no normal service life for them Things like sticks and in particular woody tree seeds will shorten their life as will sandy soils Apart from keeping the spildles and the tensioner arm greases there is little you can do other than rake the yard before you...

The purple wire should be the power return to the battery and the orange goes to the battery light on the dash if fitted I gather this is a mower you bought used

only 2 options 1) head gasket leaking between the cylinder & pushrod tube 2) faulty breather check valve or if you are lucky both of the above

Thanks for coming back The decompressors on the 31 & 33 series fail very regularly I keep seeral of the cams in stock for this reason Do not run the engine till it is fixed as the broken bits can get jambed in the engine and do more damage Not a bit repair but does require removing the engine so...

IT can be very frustrating I have run mowers for hours on end on the farm where my workshop is so the mower was working hard in mixed pasture grass and they never miss a beat , then when I go to unload them at the customers residence they play up , or they work perfectly for a coule of mows...

The bracket is prone to bending so the switch does not make full contact For now pull the kill wire off the magneto and run some wire up to the handlebars . Ground it to stop the engine

Unless you are fastideous about cleaning the fillport you will do more damage than good

There is very little difference FS-FR-FX They are all the same engine The only difference is the carb, air filters & on the FX the metal blower housing to take the weight of the Donaldson canister Internally they re all identical In the yard right now is a Z Master that I fitted an FR into...

Go to the tranny makers web site and download the repair manual then access it against your mechanical skills. The repair is not difficult , simply undo the 2 halves pull out th e old & drop in the new . many just push into place . Down side is the unit must be clean, really clean. I blow down...

None that I know of that I would recommend Lots that I would not Knuckle imparred following the dirctions of the mentally imparred is not a good idea Download your mower parts diagram Look for all the bolts that hold down the drive Usually 3 or 4 in the side around the axel and a brace plate...

Sealed for life is what the mower companies want so they do not have to carry spares for them Sealed for life = SHORT LIFE Changing the oil = Long life Now days most trannys will outlast the mower they are installed into if the oil is changed somewhere around the 300 to 500 hour mark Very few...

Check the axels Possible the wheels have been removed and the drive keys have fallen out Yes very unlikely that both have gone bad together Still could be a slipping belt but you would smell that

Be better with a bit more beefy rockers .

I fit new tyres to the outside of the rims then leave them like that for as long as possible so the tyre walls stretch out When setting the bead remove the valve & use an air duster with a big hole . Once the beads seat remove the duster and put the valve in During this time the tyre will...

Yes the transmission is on the way out Change the oil, go one grade thicker. I test trannys when unloading from my tilt trailer If I push them and they resist moving and stop the instant I stop pushing they are in tip top condition If they push with slight resistance & stop when I stop pushing...

Same as him but I use a wooden dowel in a real drill Lots of gun cleaning brushes will also do the job and they should be a dime a dozen in the USA

Different blower housing better air filter & carb That makes a difference when you mo 6 to 8 hours a day every day

Belt is too long or spring is in the wrong place

Unless you cut a really big hole in the floor, the drive has to come out

I doubt that the gekko eggs came in with the mulch if it was bagged They could have come in with bulk mulch delivered by a tip truck Cockroaces yes they can coe in bagged mulch More likely was there used to be gekkos before the house was built & gardens laid out so they lost their habitat or...

Rare for that to happen Common for debris to be blocking off the fuel outlet in the fuel tank .

Take the deck off and get underneath Watch the drive belt while some one else pushes the go pedal. The go pedal puts more tension on the belt which causes the sides of the variator pulley to move apart thus making the effective pulley diameter small so the shaft spind faster so you go faster ...

Pop , You have been looking at too many bad You Tube videos A bit of background would be helpful Owned since new ? fond on the curb ? Bought "reconditioned " I for one would start with a new fresh spark plug because they are cheap The important resistance on a spark plug is the one the air gap...

Actually all of the parts are identified by the actual drawings . JD is about the only mower maker who actually draws schmetics properly Full descriptions are on the preceeding page and the coding is common to most JD mowers. Any 1st year electronics text book will have all of the items identified .

Check that the drive belt is in the pulleys properly Some time if the brake is set you can blow it off the pulley .

Wqqant to run through this agsain I really can not visualise what you are trying to say

Blown fuse ? bad battery ground connection ?

Remove the blower housing and then remove the kill wire form the coil Engine runs = electrical fault .

Blades upside down ?

Check the pivot hole Good chance is is flogged out oval because it has not been lubed daily as the owners manual recommends .

Check that he choke is closing fully and also that you have replaced the wires on the fuel solenoid .

Totally wrong The cross hatch fills with oil and actually helps the rings make a seal It is also a good indication of wear in the bore Remember these are mower engines with castiron linners and cast iron rings not a chrome plated bore with steel rings ( although in that case the micro cracking...

Blocked tank vent

Carbon build up inside the engine or wrong plugs or running too lean Double check the coils by fitting an in line test lamp which should not flash after the key is turned off .

Valves are out of adjustment or the decompressor has failed

And make sure you find all of it . The very first job I did was replacing that retainer . Go to the Hydro Gear web page & download the repair manual for your tranny It is a easy fix but it will take you all wekend to do it properly And as Star has said, the tranny has to be clean. I blow away...

Usually it is the choke not closing all the way The fuel pump has chck valves in it and the carb has a float valve in it so if the bowl was full the valve will be closed Most will hold 10 PSA which s a lot more pressure than most can blow

If it is running wild then the governor is not working so check that both governor springs are there and attached to their correct places .

Pull the blower housing off and check the kill wire Brake on & key off it should be ground Then go open when you turn the engine on Some times the wire an fall off & some times it gets chewed throuhg over winter by some unwanted guests

And check the belt tensioner A loose belt will also do that

Well it is still a 22 year old mower regardless of who made it Your symptoms are what I would expect if it was only running on one cylinder So try to start it with one plug removed then try with the other removed Let us know what you find

To do a quick check of the flywheel, pull the nut / bolt off the flywheel and look at the timing key Bath sides of the keyway should come together the make a perfct square . Slip the rocker covers off and check that the valves are actually going in & out

Check the battery leads, both of them at both ends

Fuse might be fine but fuse holder could be stuffed pull the plug off the back of the key switch and check for voltage at the B terminal

Start with easy mechanical thingslike valve lash Excessivly loose exhaust will do this. If they are OK check the coils by removing the kill wires for a single mow ( don't forget to replace them ) Then there is a vacuum lock because the tank vent is not working so loosen the fuel cap so air can...

Blow back up the fuel line ( not through pump because it has check valves in it If mower runs and fuel lows remove thank and clean the crud out of it .

What is important is the blade heights Belts will happily run to spindles that are different heights What is important is the belt is in a strait line with the pulley If the pulley was high on one side & low on the other , that s when belt go into low earth orbit, taking yor wallet with them .

You are more than welcome HElping people & countering the rubbish on social media is what we are here to do Thanks for coming back to close the thread, happy mowing .

Which is why the make the idiot proof tool in the first place. Professionals use air guns or high speed battery impacts which only need hand pressure to hold the flywheel After that it is a prybar or two and a hammer I use a 3 leg puller with an air gun that will pop nearly every flywheel and...

You can only check the coil with an Ω meter if it has points or a remote trigger unit The act of testing with some cheap meters can itself destroy the Hall effect trigger chip embedded in the coil. coils either work or they don't work because they are not repairable So you take the kill wire off...

BEfore we go any further What condition is the engine in right now Together & in the mower or apart and on your bench ? Did it rotate a full turn with the sump off ?

Pull the top cover off and have a look You might have crud under the flywheel which locks up The front ( over the cylinder ) cover plate bolts could have come loose & are fouling on the flywheel ( factory defect ) or The counter weight may hae come adrift .

They have barbs on the back and push in To get them out you compress the barbs a sentence that is easy to say & hard to do Using a thin screwdriver compress one side and push it up just enough to keep the barbs compresses then do the other side then the ends Lots of wiggleing skinned knuckles...

FWIW The top ring is the fire ring It's main job is to take the heat & pressure from the burning gas The 2nd ring is the one that makes the seal. Every priston ring company has charts about which way to install the various rings Total Seal instructions Hastings ring identification Where...

Go for a higher tensile bolt Wack a grade 9 in there and see if it helps .

Disconnect the alternator wires and see what happens A bad rectifier can some times energise the alternator which tries to be come a very bad starter motor.

The carb float needle is not shutting off the fuel The fuel fills the float bow and eventually pours out f tha bowl vent which is on the engine side of the carb Because the carb has a slight downdraft the fuel flows bown the manifold past the inlet vales and into the cylinder Fron then it...

Take the spark plug out and try to turn the ngineover by hand NOT THE STARTER. If no petrol gushes out of the spark plug hole then secure the spark plug out of the way & try with the key Let us know what happens .

Never seen a fan fail Seen a lot of them fall apart because debris has been tossed up into them So I would have a long hard look first because this will be very expensive if you get knocked back .

!0 NO the solenoid is double sealed so it can not leak but the thread around it can if it s loose It is a 1/2: flat so you need a very thin 1/2 spannar to get in there 2) if it is leaking and the solenoid is tight then it is comng from bowl vent hole . Usually this will leak into the engine but...

Commercial bearings or Metropolitian Engineering supplies Post from Australia might be a bit steep however .

To dissengage the two brake pads have to be able to stop the pulleys moving so the slack will end up on the engine pulley And of course the actual belt size and profile has to be correct there is more to belts than lenght & width

They sit on top of the cam It is the automatic decompressor Kohler have their repair manuals on their web site as a free download

Reasons why oil leaks from carb 1) bad float valve allowing petrol to drain into te sump when not in use thinning the oil 2) engine being tipped to far with carb side down 3) oil level to high

There is no way for engne oil to enter the carburettor other than through the breather tube Usually what happens is people tip the mower carb side down so the sump oil fills the breather chamber and from thee has to go into the air cleaner housing .

And I apperciate it is the gimmick but will every one else, particularly those who get a skinfull then decide to go fix something . You can chop off fingers doing repairs just as easily as while mowing. Now if he ended every video with "Job done now it's time to celebrate with a XYZ beer" that...

I put a pair of scissor jacks between the body and the wheel to apply some load on the wheel & axel Then I lean into it with an air hammer on the axel When the jacks slide out I tighten then up again & repeat . When there has been about 1/2 of movement the wheel, wire brush the axel & run some...

While Steve is reliable I can not condone drinking beer while working on engines I do get the "saloon" bit but not a good idea .

At the battery Check voltage engine off Check voltage engine running Check voltage engine running & PTO engaged Both of the latter must be between 13 & 15 volts Flick the multimeter to AC and do the last 2 tests + terminal to ground If you get a reading higher than before then the rectifier...

Not sure if this should be a thread or a poll but we might just start here and see where it goes Rahter than critisize bad ones I though we should prais the good ones and holefully we can point those new to doing repairs to this thread So I will kick it off with some of the better ones I have...

Yep stone dead Now if the kill wires have diodes in them then test them as well lest they lead to a very short service life for the replacement coil. And make sure you get the correct one or the engine will never run properly Also test the kill wire for voltage It is a ground wire so should only...

Good point Perhaps we should compile a list of You Tubers who are worth the effort of looking at. However this might get a bit tricky Steves Small Engine Saloon for instance has good reliable information apart from one thing Never touch an engine if you have been or are drinking booze I have...

Wrong cable Wrong spring Cable anchored in the wrong place Wear in the tension arm allowing the deck pulley to foul on the engagement cable Cable routed over the belt rather than under it or visa versa They are the common ones .

Unless you are towing or driving up a massive hill the engine will be running on the idle circuit in the carb because it not under significant load. Whe you turn the blades on you add a high enough load to cause the main jet to come into play The same thing as pushing the governor with your...

Have you actually contacted Echo directly ? and no I do not have any coils for them in stick. Finally I am in OZ

I will guess that you set the valve lash at TDC on the exhaust stroke and not on the compression stroke. A common mistake we all make every now & then So from scratch rotate the engine and watch the valves move with the spark plug removed The lower ( inlet valve) should close ( rocker goes...

I like to run a customers mower for at least an hour before I hand them back Even with this field testing a couple always come back

Just to clarify things The magnetos have a Hall Effect Trigger chip in them which is what makes them work They have a kill wire attached to stop them working when you shut down . On twin cylinder engines you get a ripple down the kill wire that can interfear with the other magneto so they put...

I fit standard idler pulleys bought from an engineering supply company They come with jst the bearing in the pulley so I have to push the old stand off bush out of the old pulley and fit it to the new one All of 2 minutes work that halves the price . And reduces waste to boot .

If you have a V twin Briggs in there then the engine numbers are stamped into one of the rocker covers , As the covers are identical & symeterical they often get put back ( guilty as charged sir ) upside down or on the wrong side The first 2 numbers in the model number is the displacement in...

Well that only leaves one or both of the cams being out of time with the piston movement So yes time for the scuba gear and deep diving into the engine. Nice thing about this one is you do not have to remove the engine from the mower, just slip both belts off then take the top cover off the...

We need to know what engine is fitted before we can give you any meaning full help .

Looks like the intake valve seat has come loose , intake vale is stuck & not closing properly , head gasket is leaking Remove the breather tube from the back of the air filter and repeat what yo did in the video If it stops blowing excessively out of the carb then the head gasket is gone and...

Welcome Please remove this thread or the other identical one Having the same thread duplicated get confusing and quite a few tech see this as being agressive so ignore people who double post As both are in the same section and only a few minutes apart I guess it is either fat fingers, sticky...

From the first reply to the same thread that is double posted which explained how to diagnose the no start problem Put your jump start pack directly on the engine block then touch the + to th + termianal on the starter motor. If the motor spins a lot faster then time to check / clean / replace...

Engine spins X number of times, fuel is sucked into the engine then blow ot of the exhaust unburned because the air"fuel ratio was wrong or the spark plug is bad or the spart is at the wrong time Some of this is blown out of the exhaust while some stays in there Then the engine finally ignited...

Back in 1962 som Hungurian Immigrants to Australia invented the Hall Effect ignition timing chip The company was named Atom and for the next 30 years they marketed their invention as the Atom Ignition module. It was a stand alone points replacement . Husqvarna paid them royalties as did OMG for...

Sounds very much like you have manual PTO's on those decks Despite every owners manual showing to oil all of the moving parts daily, no one ever does it So pivot holes flog out oval tension arms wear on the bushes so they go out of alignment springs cut through ther mounts and drop off contolr...

No drain bolts on any carbs other than Honda ones usually you can just remove the solenoid to drain the carb To do that you just need a very thin bladed 1/2 spannar although depending upon the position you might needt to do come custom bends I have about a dozen 1/2 inches bent to all sorts of...

poke your nose down the carb and make sure the choke is closing ALL THE WAY. 'If not loosen the clamp and pull the cable away from the engine till it does. Now this might mean the full speed indent on the control lever is now in the wrong position You will just nead to live with that

move the coil back another 0.005" This will retard the ignition a poofteenth .

Jump directly from the battery - to a good ground near the engine Engine cranks strong = bad grond cable / connection Jump from the battery + to the + post on the starter Engin cranks strong = bad power cables / connections Engine cranks slow with both jumpers connected = bad starter or...

Backfire or after fire ? Most likely either a bad plug or bad safety switch Pull the kill wires off and see if you can eplicate the backfire Yes = bad plugs No = bad switch

Start with a wiring diagram other wise you are just shooting at noises in the dark Make some short jumpers ( we call them patch cords for some weird reason) with a male blde on each end. Go through your safety switches one at a time any bypass the switch by jumping the terminals try a key...

OK so that only leaves the flywheel key broken and the engine is out of time or something horrid inside Pull the blower housing off Remve the nut / bolt that holes the flywheel and heve a very close look at the key waay slots The on in the flywheel & the one in the crankshaft should de aligned...

No All screens are easily removed for cleaning However I have seen many that really looked likea solid piece of steel they were so badly clogged . It may have never been fitted from the start It could have fractured & fallen off If you have taken it to a shop for repairs it could have been...

etting off topic a bit but I was at a brainstorming session a few years back. I was on a table with another club president & 4 young people from the departments I section. every time a topic was brought up they were worried about how they could get & capture data from it . Eventually the other...

debris can build up in the fuel tank and fuel lines which blockes them ogg Try blowing back through the fuel line .

The timing is set by the flywheel which has a key in it which can shear Next step is to remove the rocker cover, rotate the engine by hand and check that the valves are mving in & out .

They fall off and people take them off becuse they are too lazy to clean them

Spray a short shot of starting fluid ( i like t use carb cleaner down the plug hole and with new plugs try again If the engine fires and runs fine a second or so then stops but would not fire with starting fluid sprayed down th e carb throat then one or both valve are not working. If you have a...

remove the kill wire for both coils and see if the problem goes away .

On more than one occasion I have got to the checkout to find is is all self scan So I just leave my trolly in the most inconvienant spot and walk out then go shop somewhers else One time I had over $ 1000 worth of stuff and got challenged at the door by the shop manager So I flicked the wad...

That should take he standard domed Husqvarna seat switch So just cut a round hole in the new seat base and bolt the switch in. If it does not work, scoop a SMALL amount of foam out. I regularly fr bot seats to ride on becaus they are 1/3 the price and a lot more weather resistant Never had a...

Just tie it up some where out of the way From now on when you have done mowing slide the throttle down to the lowest setting count to 5 and turn the key off or you will get an after fire in the muffler. They don't actul;y do any damage but as they can happen anywhere up to a minute after the...

Yep or was assembled wrong I gather they are both used engines Most mower engines will run 1 tooth out .........badly

No but a head gasket is cheap and it only takes about 1 hour to change Cheap and nasty test for rings is to work the throtle valve by hand Worn rings will progressively blow more smoke as the throttle is opened and leave an oily deposit on the spark plug A leaky head gasket will not leak then...

As we do not have tier II pollution laws for mowers here yet you can snip the end of the valve off However they rarely ever go bad. In 11 years I have only ever replaced one . What does happen is the ground wire to the solenoid breaks off at the terminal where it is bolted to the cooling shroud...

Can be dirt & debris in the fuel tank Cracked or broken fuel pick up in the tank Blocked tank vent ( loosen the fillercap to cheack ) Deterioated fuel lines This assumes the fuel pump is good .

And do this with the engine running as slowly as possible with the wheels jacked up clear of the ground.

You can put any engine into almost any mower . Down side is controls may not fit or be different , electrical plugs will be different and muffler will not fit and the latter are quite expensive . If the ARC has failed then the engine will do 1.5 revolutions then hang on compression, slowly go...

Ring around & check Most would not because they do not have engine stands because they no longer do engine rebuilds It also knocks off 2 to 4 billing hours if and only if the engine needs removing Top end jobs are all done engine if mower as are lower oil seals

And your chances of finding a good one are not much better than winning the lottery twice, without a ticket. The first bit that falls apart is usually the muffler. Mower engines are not tuned so the muffler is not particulartly important for any reason other than preventing fresh ait contacting...

The seat or reverse switch is not working properly so it shuts down the engine by killing the magneto Because it only kills the magneto the sarb solenoid remains open so you get an after fire through the exhaust If you have the 4 wire flat plug on the seat switch undo it spray some contact...

You need to remove the air from the tiny little pistons It is called purging Some times it happens in 5 minutes some times it takes all day what is vitally important is the wheels must be off the ground so there is no load on the motor and the engine is running as slow as it will run

Muffler clogged ? Loosen the muffler bolts and see what happens .

You won't know till you look You could have a bad diode on the kill wires , so a 5 minute job You could have excessive valve lash a 10 minute job the longest & hardst thing to do is find the problem It could be nothing more the crud rolling around in the petrol tank Now we can help you find the...

If the engine dies like you have turned it off then it will be electrical If it sort of peters out then it could be a bad cylinder

Different belts but it can be a loose engine mount or a loose hydro mount ing bolt or brace plate between them They hydro maker will have a service manual on ther web site As mentioned before JD ( and others ) fit non servicable hydros so it absolves then from warranty claims and means they...

FWIW I fit a long stainless coach bolt to hold the battery terminals on because of the square section under the heat the bolt makes a good contact with the post . I use a wing nut to hold the terminal to the post then paint over the whole lot with "liquid Electrical tape " thus the different...

The starter is not strong enough to turn the mower over . This is deliberate so in a hydro lock the starter stalls rather than blowing out the spark plug, blowing the head gasket or bending a conrod To overcome compression pressure the inlet valve opensa tiny amout to let some of the pressure...

Yes the terminals must be flat against each other and not being in full contact can cause arcing The watr analogy is tipping a ful bucket of water through a narrow funnel Some will pour over the sides if enough can not get through the small hole .

Yes no aruement from that Apparently the population problem will be self correcting . Seamen levels & strength in Western countries is decliningat the rate of knotts according to a UK lecture I listend to last week So while all of the reseach has been done on the woman , the actual problem is...

Dirty float needle causing fuel level to be too high

Nothing on your mower The same carb comes air primed, fuel primed or choked

OK Get some one to hold the brake down and feel the slackness in the front belt Then put the speed controller in the brake position, let the brake pedal off and adjust the nut to get roughly the same slackness in the front belt Don't over do it because that will prevent the pedal from going all...

FWIW Apart from hat I posted on the other place your thread is I have seen hydros fail within 100 hours There is a Craftsman in the shop at the moment with 78 hour on it and both hydros have failed . Now this is owned by a buildng company who have a small yard with a lot of trailers for things...

When the valves get hot they expand so the shaft becomes longer If thee is no gap betweenthe end of the valve and the rocker ( the bit that pushes it down ) then when it gets hot it will not properly easl agains the valve seat so some of the burning fuel will escape past the valve rather than...

Nice reply from Cajun However I need to point out that the carb solenoid prevents fuel from going through the main jet into the engine . It does not stop fuel overfilling the float bowl then entering the engine via the float breather which is a hole on the engine side of the carb . It is a...

LEft drives always fail first because the belt tends to slip on them and the dust raised form the deck tends to coat them more than the right. This design problem is made worse if the owner does not pay attantion to lubricating the tension arm pivot and keep the hydros clean so they can cool...

Hydros are very expensive to repair and not usually done by dealers as the franchise wants you to relace the entire unit This is a quick & easy fix fo them and puts the warranty on the hydro suppier

The parking brake sensors assumes it is still on so shuts down the engine to prevent damage to the parking brake IF you have a stand alone brake ever it will be on the end of that If automatic brakes it will be on the end of the lap bars .

Welcome Could you tell us the make of engine fitted ? If you do not know it then take a photo and post it . Note most phone plhots will ned to be resized in a photo editing app Make it 12 " along the longest side, set the resolution to 72 dpi and the file type jpg You are correct, the batttery...

If you replaced one, then yes replace the other one The coild have a Hall effect timng chp in them that replaces the points ( remember them ?) The chip measures the tiny change in coil voltage and is very easily damaged . I have never gotten away with just replacing the coil that was not firing...

Remember thiis is not a fix just a diagnostic test B & S put the diodes in the loom so they are replaceanle Kohler use much better diodes but unfortunately they are embedded so it is new coils time And you have to relace both of them .

Ant time you feel I need correcting please feel free to do it I do know what it is called but as it is as EPA regulation I refuce to use the term thta implies it was there for the benefit of the owners As for shut down speeds the engine runs at a fixed speed so it is nothing like puting your...

White smoke is oil Remove the air filter and see if it feels oily A blown head gasket can over pressurise the crank case which causes oil mist to be blown out the breather tube & into the engine A bad breather valve can have the same effect Too high oil level also does the same thing .

open you photos on your computer in any app that will read & display them Change the size to 12" on the longest side & the resolution to 72 DPI Then save them in jpg format Thuse will upload and display full size on a computer . Phones store inRAW format so they can get good detail and write...

Pull the kill wires of each coil If it runs fine like that replae both coils. There is a diode embedded in both of them that prevents then talking to each other via the kill wires Not a very common problem with Kohler coils but does happen. No possible repair both coils will need replacing .

Funny you should say that I have been having problems with a customers Z225 as well Similar story I replaaced the fuel pump as well. ran fine for a couple of days then died in the yard Changed the fuel pump for a better one, same thing. put new fuel lines & impulse lines on it, ran for one cut...

The problem with capitalism is it is very wasteful of resources because of the asumption of endless supplies of everything IT also assumes that consumers and producers are equal and there is a limitled supply of both. Then there is the assumption that "The market is informed " Tried to wade...

White smoke , black smoke ?

No In the bottom ofth fuel bowl is a fuel shut off solenoid that shuts off fuel TO THE ENGINE when you turn the key off . BEcause it is at the bottom of the float bow it gets gummed up when the fuel evaporates Then it does not open fully when the key is turned on.

Bog down ? When a goverened engine runs out of fuel it cycles a few times, so it slows down, then speeds up then slows down then speeds up etc then stops . Is that whatyour mower does ? or does it just start running slow then stop ? Wht engine does it have in it ?

Stale old fuel gums up the small passages in the carb and also the solenoid on the bottom Sloshing seafoam around is not a solution The carb has to come off for a proper cleaning and the solenoid will also need to be cleaned . The gummed up carb will have leaked fuel into the engine as per the...

It is some thing I have tried to get through peoples heads for ages The actual numbers are not as important as them all being the same I play with vintage & veteran motorcycles and it is a daily refrain "What is the torque ona 19xy ABC ?" Well prior to the 60's a tension wrench would only be...

Just so we are singing from the same song sheet You are saying that the drive belt, the top one that connects to the hydros jumps off when you turn the belts on ?

Thanks for posting that I have rubbish internet so searching for a good clear chart was never going to happen My guess it is a bad translation Thread shear on a 10 x 1.5 mm bolt is 42 ft lbs but the alloy will yeild way before that 30 to 35 ft lbs depnding upon composition & temper .Considering...

Pull the plug off the back of the ignition switch and check the red wire for battery voltage. Some JD's use a fuseable link as well as a fuse As I have no intention of rewrithing the 137 page JD electrical system manual we will do baby steps If you have 12 V on the red wire, make a patch cord...

K I and othere would love to help you but your post makes absolutely no sense So sit down and have a think and describe the problem you are having in detail

Kevlar belts do not stretch Even plain pollyester belts do not stretch very much and some actually shrink . Belts wear thin on the sides so they sit deeper in the pulley and become loose SO if you see a thin spot that is because the belt has burned . This happens because the belt is stationary...

38Nm is 28ft lb which is on the high side for a coarse thread zinc plated bolt into aluminium castings 38 ft lbs will strip the thread out of the hole So I will guess that the translator forgot to convert the Nm figure as used in China to Ft lbs as used in the USA. Break away torque is not a...

Never seen a 4 stroke Suzuki engine on a mower down here but I service 5 Toro's fitted with the Suzuki 2 stroke engine. The only time there was a death problem was with an inherited one and because the new owner saw an oil filler assumeed it was 4 stroke & ran it on strait petrol for a full...

I have occasionally resorted to loosening the bolts to give me that 1/32" that was needed t get the SOB belt over those pulleys

Low oil and in particular low oil running along a slope can deprive the top bush of oil so it runs dry for a couple of seconds then the aluminium rips out and welds to the steel crankshaft. It is a common problem particularly on gravity fed engies as people mow carb side down which means it is...

I have no idea where you got that chart from but oil is a liquid Being a liquid is has NO SPECIFIC DENSITY because all liquids expand with increasing temperatures the viscosity index is nothing more than the amount of time it takes for a specified volume of oil to drain through a specified size...

Yes and not really Mower & stationary engines are not performance tuned

Welcome !2,5 HP is insufficient information to give specific advice as we need the model numers off the rocker cover ( OV engines ) or blower housing near the spark plug ( SV engines ) IF you have never adjusted the valve lash, now is a good time to at least check it

Welcome Full description of "Not Cutting Right" please

Solves the dust problem as well Farmers do a lot of wet blasing as it is very hard to get a 1000Hp tractor intoa blasting cabinet . So tractor shops or stock & station agents might be the way to go .

A lot of push mowers have a handle that goes down at the operators end. Most of these can be flipped over to go up raising the hand height . Some mowers come with strait bars and another model in the range has downturned bars and these can be swapped over. Problems may come with control cables .

There is a cut off solenoid on the carburettor that blocks the supply of fuel to the engine. IT needs 9V DC minimum to stay open So your mower has a problem in the charging circuits as it should be making 13V to 14V off the alternator which in theory should be enough to hold the solenoid open A...

Overheating without surging is either timing slightly out or a build up of dirt around the cooling fins. When oil gets too hot it gets too thin so the oil rings can not scrape the oil off the cylindrer oil. SMOKE tells us nothing without the colour of the smoke

Gord, Powdered graphite is to lubricate key tumblers Graphite is conductive so not a good idea to put it in a switch.

NO Worn rings will cause the plug to oil up not the crankcase to fill with oil. That can only happen due to a bad fuel pump ( where fitted ) or bad float needle ONLY 2 causes You have been watching way too many brain dead idiots on You Tube .

The tension arm pivot wears as does the pulley and the spring looses tension over time All of these will cause a rattle as will a small nick on the belt or a flat spot on the pulley or some crud stuck in one of the drive pulleys

JD specify a lower viscosity oil in their transmisions . Most of them start to go at around 1000 hours So if you now own this mower and it has a hydro tranny pull the transmission out then drain the oil and replace it with 20w50 fully synthetic engine oil. That should give you another 500+ hours...

1) sharpen or replace the blade 2) adjust the valve lash ( see You tube videos ) 3) remove the engine cover & clean the fins on the engine IF this does not make it 100% better come back for more information

Unless it was really low very unlikely you have done damage to the bore Usually it will be either the little end or the top crank shaft bush that go dry first Worth pulling down to check Continuing to use it will destroy the engine

Not many places to check Why do you think ou are not getting any fuel ? better than average chance that the choke is not cloosing fully I would drop a 1/4 teaspoon of fuel down the carb throat or spark plug hole See if the engine starts and continues to run for a minute or more Let us know...

Nice job and good information. Now to do the wet towel bit Does you mower need an oil cooler ? very few do Oil needs to be between 80C and 120C to work as the factory that made the engine expected it to. Oil coolers for motorcycles were all the rage in my youth and like all the other teenage...

A lot of businesses down here who retail Chinese junk swap over any purchse that breaks down in the warranty period ( 12 months) for a new one. Now the faulty ones are either stockpiled by the importer to be auctioned off after the warranty period has expires or they sell them, again at auction...

You bridge pin 30 & 87 or 30 & 87a depending if it is a normally open or normally closed relay to bypas the relay Test the relay by energising the trigger terminals Most are not polarity sensative but again most relays have their circuit printed on the top of the cover
