I am not talking about the mower deck belt. I am talking about the belt that goes from the engine pulley to the hydrostat pulley, which is basically tucked up inside the frame rails. Item 50 on this diagram...

Have your looked up inside the frame from the underneath to determine that the belt is still in one piece and not came off and all the idler pulleys are in good shape.

And everything you just posted has been proven false. Some of it may of been considered true years ago, but with current fuel formulation is all false. Higher octane reduced pre-ignition but has the same burn rate and btu output as 87 octane.

All of the premium small 2 stroke manufacturers, aka Stihl Husqvarna, Makita/Dolmar require a minimum of 90+ in their products to prevent pre-ignition which will cause engine damage. But premium fuel doesn't burn any hotter than non-premium fuel because it has the same btu rating. The only...

When you move the throttle on the carb what the governor arm and check to see what direction the shaft rotates when the throttle is moved from idle to full speed. That is the direction that the governor shaft needs to turn to set static governor position. So if the governor arm moves down then...

Sounds like something floating around inside of the jet assembly item 117 on this diagram https://www.partstree.com/models/9p702-0145-f1-briggs-stratton-vertical-engine/carburetor-4/

You can unscrew the cover if it is the one I think it is and then install the 690954 oil filter nipple, and then install your oil filter.

Yes. The only gas I have in the shop either is 91 non-ethanol or 93 with 10%.

The OHV push mower engine are fuel picky, I would try draining the fuel, and putting in fresh fuel that is recently purchased. I have seen mowers from customer that claim they are using fresh fuel and I can't even light the stuff with a lighter. Just because the fuel works in everything else...

The Pro/Commercial engines are just Intek twins with upgraded features which are below the quality of the Vanguard engines. It should bolt right up, just make sure the crankshaft diameter and length match your current engine or the specs of the 44T977-0009-G1 Looks like the 49T877-0009-G1 has...

Owner replaced keyswitch. Can we confirm that it was the correct keyswitch.

Wouldn't be a bad idea to check the valve clearances to see if that helps. Could also be a dead spot in the starter.

Looks like the Briggs recommended engine to replace your current engine is a 44T977-0009-G1 That will be the only direct drop in engine. The Kawasaki engine will also require new exhaust possible wiring changes, etc. The Briggs Commercial engines are all variations of the Intek twin and...

Could of been a looped jumper between the two connector pins

Governor gear is inside the engine crankcase. So if that has failed then it is engine removal and disassembly time

Could be possible pending crankshaft length and diameter. The mount pattern should be the same

I would suspect that either the bolts have come out of the throttle butterfly and the butterfly is stuck open, the throttle shaft has broken or the governor gear is broke and not controlling engine speed.

Hydraulic lifters therefore not clearances to check

Sears isn't the only one. Add Husqvarna/Poulan Pro for total customer refund of money for a blower that the battery went bad on 3 months into a 3 year warranty and the battery was NLA.

Nothing adjustable outside of grinding the stem of the valve to reset the clearance

If you are engaging and disengaging the deck a lot that can eat the brakes. But typically the one on the engagement arm item 63 is not usually the problem. The one on the other blade spindle item 60 will either get installed incorrectly and flipped around backwards or the rod item.64 will...

Most likely not cost effective rebuild unless you get really really lucky and nothing inside the engine is damaged Most likely 99.9% chance will require replacement engine. And your response is typical of people that never realize that they are only running on one cylinder. People just...

That is OK, Glad I could assist. What is really bad is when MTD will put a letter on a diagram, and the corresponding letter is on another diagram.

Looks like 491255 label kit which is NLA. No longer available

Your cut off part of your diagram. G is next to the pedal at the bottom of the same but complete diagram https://www.partstree.com/models/13ag601h729-yard-machines-lawn-tractor-2005-home-depot/drive-1/

Working on a Command CV730 and while doing the carb kit discovered that it also need the accelerator kit. The carb repair kit is $68 and the accelerator pump kit is $104. Can get a complete carb assy plus gaskets for $35. For $35 worth ordering just to steal the parts off of to repair the...

Is the engine running at idle or mid throttle or full throttle. That info would assist in direction of problem. Are you certain the throttle was installed incorrectly. If the carb has been removed are the carb linkages installed correctly. Will the engine change speed of your manually...

Totally agree. I am not buying the rust story unless those pulleys are deep pitted with rust.

Same for me when they were in Jasper. Now with them in Tennessee and Fedex 2-3 days is now normal. Same thing happened with Power distributors going to Fedex this year when from next day out of Columbus to 2 days out of Iowa and now 2-3 days with Fedex from Iowa. And to make it worse PD...

Partially blocking the intake and running fine indicates a fuel delivery issue. So either the new Honda carb has a problem or you have an air leak between the carb at the intake manifold, or an air leak at the manifold to cylinder interface.

That is the Digital Spark Advance Module or DSAM for short. It controls spark timing and advancement. When it fails can cause a no spark issue. When doing the DSAI conversion that box can be removed and tossed in the trash because the conversion doesn't use it.

Here is one possible place to get the DSAI system if you need that setup https://www.amazon.com/Kohler-12-707-01-S-Equipment-Ignition-Manufacturer/dp/B00TD633W4

Little more complicated than that. On his engine he either has the DSAM which supplies 12 volts to the coils, as well as impulse controls and has 2 terminals. The DSAI conversion also supplies 12 volts to the coils and has 3 terminals. You can't just unplug them and make it work like the...

And customers wonder why it takes so long to get their equipment looked at or repaired, And the tech is wondering why they don't get anything done.

If that is the correct spec then that is a DSAM engine so may need the 12 707 01-S DSAI conversion.

Well the ATV had the main jet fall out of the carb so that was an easy fix. The Troybilt carb work went fine and was returned to the customer. The Kohler 25 with the blown head gasket has had the gaskets replaced but is running rich and dumping fuel into the oil, so doing a carb repair on it...

The spec number along with the engine model number would be helpful so we can look up the correct engine. Also if this has the single wire coil unplug it and crank the engine. No spark then bad coil or plug. the reason I ask is some of the CV16 has smart spark ignition on them.

That is not the engine model number. The engine model most likely is stamped into the valve cover Should say model, type and code above the information. And if this is a single cylinder Intek engine then one or both of the following has happened. the valves are out of adjustment preventing...

It looks like your spring has a B* next to it on this diagram. https://www.partstree.com/models/ltx-1842-13ap609g063-troy-bilt-42-lawn-tractor-2003/pto-drive-battery-frame-components-6/ Which then corresponds with the B* on this diagram...

Might need shimmed up slightly, and looks like the idler arm original hole was the left hole.

Do you have a MIL light on when this happens. That would give some direction to the problem. But sounds like the issue starts when it goes into closed loop. Disconnect the O2 sensor and then start it and see what happens.

I suspect there is a ACR issue not releasing compression to crank the engine. Have replaced the ACR on the camshaft a couple times, but ends up being a temporary fix. Have also had to replace the cam gear in conjunctio with the ACR but even that can still result in intermittent issues.

And you are lucky that the batteries haven't been obsoleted forcing you to purchase a new mower.

Not surprised at all. Sometimes if you look at regular motor oil. The quart bottles are cheaper than the 5 quart jug. And I have even found cases where quart bottles were cheaper than 55 gallon drums.

Depending on brand of tranny used parts may not be available, and either way would require disassembly of the tranny to remove and replace the axle.

People on this site have used them with issues. Parts Direct will bill your credit card at time of order even if the part is not in stock and backordered, but the part will show in stock on the website. Their site has been goofy since Sears shutdown, so I don't know if I would trust them other...

I wouldn't be afraid to throw another new spark plug in and see what happens. Your no start on starting fluid hints to a lose of spark. So either spark plug or ignition module is doing a heat soak failure type scenario.

The 25 098 11-s supercedes to 25 098 20-S which supercedes to 25 098 21-s which brings us to the current 25 098 24-S

I agree with your assessment. Have a Kubota D902 in a Ditch Witch Mini skid that is a pain to start cold below 40 degrees. I take that back. Fires easily with glow plug but because of the hydraulics kills the engine. The Kubota owners manual says to start at half throttle, which I hate...

Tecumseh basically went belly up after the bankruptcy and sales of Murray since Murray was the largest user of Tecumseh engines. Tecumseh was purchased/taken over by an investment group. That same group has control of LCT engines and the combined name for both is Lauson engine, which was the...

Tecumseh went from the 4 bolt system to the 2 bolt in the early 2000's seems like there was a bulletin discussing it.

I would recommend putting a small amount of gas into the intake and see if it fires and runs on it, but there is also a chance that it flooded out, and adding gas could make it worse or give a false symptom leading down a non needed rabbit hole. Try cranking it first without the choke on and...

You are getting 6-7 volts because the starter is shorted which is pulling more amps than the wiring can handle therefore causing a voltage drop. The best way to determine what starter you need is to look up the starter by using the model and specifications numbers from the engine tag. You...

I suspect that the magnets that are supposed to be glued to the outer housing are loose and broken, So probably nothing to loose taking it apart because most likely it is already junk.

I don't think people realize that mowers have at least 3 different manufacturers with their own problems, services, and warranty. Also that the number on the hood is just a series number and can have several different models within that series. And that doesn't take into account the 3rd party...

We need the actual engine model number and Specification number(spec number for short) and engine serial number from the tag on the engine. T2400 doesn't tell us if it is a CV or SV or KT.

Kohler recommends full throttle shutdown due to how their carbs are plumbed. Kohler setup doesn't shutoff the idle circuit of the carb with the fuel solenoid. So idle shutdown allows fuel to be drawn into the engine and unburnt into the muffler increasing the case of afterfire.

Rust not manufacturer issue. But paint in the belt groove can cause all kinds of havoc on belts and should be considered a manufacturing issue, not a defect in quality but in workmanship. But I say the OP either has a belt alignment issue or could be something like welding spatter in a pulley...

Agree Rivets. Could be something as simple as a rough area on a pulley that is filing the belt down. Had a rider years ago that had issues with damaging the belt because of paint that had partially chipped off of the pulley in the groove and was acting like a knife to the belt.

May also want to pop the fuel line loose from the carb and check fuel flow through the fuel line. Should be full flow and if trinkling out means fuel restriction. I have seen the fuel filter that gets inserted into the fuel outlet on the fuel tank collapse and cause flow issues. Also some of...

See original post https://lawnmowerforum.com/threads/407777-0124e1-carburetor-float.76541/

Next time it stalls try loosening the gas cap and see if it will restart. Also could try putting a small amount of gas into the carb intake and see if it starts and dies or continues to run. Or doesn't start at all. May want to recheck the model number because it is coming back to a 1993...

Can't find any specs that used the solenoid shift starter on the SV735, But was used on one of the SV740 and 3 of the SV730.

Go back and check your spec number you are missing a digit. And Kohler OEM starters normally have the part number on the starter housing.

Looks like the float pin is still in place at the bottom of your picture. That has to come out to remove the float. If the float doesn't come out then the float valve is stuck and will need to be pried out. then you can get to the emulsion tube screws after that.

Most of the courage twins used the non solenoid shift starters. If you are looking to do the conversion to the solenoid shift starter version see this thread https://lawnmowerforum.com/threads/sv740-starter.76195/ Which has the part number for the solenoid shift starter that I used on the...

Lets start with the actual model and serial number from the tag on the mower since P510 really doesn't mean much. Also numbers from the engine may also help.

If they have them they don't even share them with the dealers or service centers.

I will give you a heads up. 3rd generation starter doesn't fix the starter issues

MTD made in China engine not Briggs as thought

I tend to steal the battery cables off of junk riders for reuse.

That looks as fun as the struck mini dozer that I worked on years ago that had a 16 hp Tecumseh engine in it.

Had a rider a few years back that had a faulty relay, and MTD tech support at corporate told me that model didn't have relays. The funny thing was this mower had 3. Had one after that were the positive battery cable had been cut while sitting on the store lot so they could steal the battery...

The truth is I don't think MTD even has wiring diagrams for their products. I suspect that the harnesses are third party and that company just builts the harnesses to MTD specs and doesn't have a set wire color schematic

Get me the model type and code from the Briggs engines. I can get into the the MTD system and find a model number or several that used that engine for a certain year that would narrow down your possible matches if the diagrams list the engine used..

Busy here also, but seems different. Not the normal simple repairs that take 30 to an hour to repair, and complete several a day. More of the less pieces but the stuff where 1-2 pieces is an all day project. Currently have a Honda ATV that is blowing black smoke after warmup. A Troybilt...

Non screw in dipstick on the norm across most brands. Honda, Kohler, Kawasaki, most of the foreign stuff sit the stick on top of the thread. Briggs is the only one I can think of that is screw in to check.

Remove the blower housing disconnect the single wire going to the coil and test for spark with either a good spark tester or a know good plug. If no spark replace coil. People that think they can test the ohms of ignition coils used on mower are just blowing smoke. And not the smoke that is...

Due to the issue with possible worn shaft starter bushings it could also lead to the starter dragging due to the armature hitting the magnets requiring extra amps to turn.

They don't give those wheel spindles away either. One shows NLA the other shows 2 in Briggs US distribution warehouses, but the pair if available would set you back $325 US dollars.

Very common starter issue. Just replaced the starter on the BIL mower a month ago because that exact same starter that you are having issues with sheared the shaft off even with the housing. Issue totally set me off so I rewired his mower for the Command solenoid shift starter...

OP hasn't been seen since May of 2015 so we don't have an answer and won't get one.

Post the model, type and code number from the engine. Numbers may be on a tag next to the air filter, but also could be stamped into the side of the block on opposite of engine as carb.

What is that electric connector behind the cable in your third picture. Most likely that is the pto safety switch connector.

Make sure the pto cable is pulling the engagement handle all the way back against the stop when disengaged. Or try pulling back on the handle while attempting to start. The pto safety switch is tucked up in a hole behind the right fender.

I suspect that when adding oil it displaces the air in the crankcase. that air escapes from the breather which it should. The breather is connect to the air filter housing which could be were the sound is coming from

Sometimes the oil spec is for a dry engine. After oil is added the first time it doesn't all drain out. My nephews stump grinder has a Briggs Vanguard 35 hp engine. The books calls for 78-80 ounces of oil. It has taken 64 ounces to refill after oil change since the day it was new, except for...

Get the actual model,type,code from the engine as well as other features of the mower such as deck size bagger or not etc. Sometimes the model number can be found by narrowing down the possible models to a year. Also the cable cover may have the part number stamped into it.

The Briggs single cylinder Intek engine such as your has a history of blowing the head gasket between the cylinder wall and the push rod cavity

Popped out, install new sealing grommet and then press the vent back into the grommet. Put a small amount of lube on the part before pressing to make installation easier. I normally use dielectric grease.

Welcome

Exhaust gasket and bolt should fix it/

Pipes should be fine, but may want to look at them a little closer. The muffler has some surface rust but otherwise looks OK also. Could possible be a leaking exhaust gasket which could cause more noise. If you look around were the pipe connects to the engine you may see evidence of carbon...

Could be a problem with the equipment wiring, or key switch is faulty or the key switch isn't grounded allowing the coils to ground.

You will also need the spec or type number to narrow down your engine variation. Should be on a tag along with the model number. Depending on year could be a metal tag affixed to the block. Or stamped into the rewind housing or a sticker on the side of the rewind housing

Best you can do is remove the unit from the mower and turn it upside down with the vent/fill plug removed and drain as much as possible. Fill within 2 inches of the top and then air purge it and then check the oil level through the fill hole. Adjust level as needed.

81 ounces of 20W50 motor oil. spin the input shaft with a drill while performing the air purge procedure before reinstalling the unit. Oil level should be around 1.5-2 inches from the top after purging.

Teflon tape not required. It will seal well enough with just being installed and tightened with the air filter base installed

Just as a side note. On some of the Tecumseh engines one of the air cleaner base mounting bolts goes into the primer cavity and if the cover is not installed or at least the bolt it won't prime. Also if the bowl gasket isn't sealing they won't prime either.

I was disappointed. Not as dark as I expected. Peaked out about 2:03 for me and by 2:07 you couldn't even tell there was an eclipse. For the welding helmet. It worked up until about 75% coverage and then the available light wouldn't trigger the sensors on the auto darken. Lucky for me I...

I have at least shade 13. And people have been using welding helmets to view eclipses for years, so why is this one so much different.

Everything from bent linkages to wear to the height control lever being bent due to people snagging it on trees when they drive by.

From the mapping it looks like I am 99.79% obscuration

Same here. I will just grab my welding helmet.

One of the diagrams shows the seal being held in with a snap ring. Probably the easiest to just remove the charge pump cover and then work on the seal replacement on the work bench. Just make sure that the square end of the cover faces the control linkage as in your picture otherwise the...

Model number was correct but looks incorrect because of the copy and paste from the Ferris parts diagram.

No parent model for the 5103443YP but the 5103443 comes back to a PK-3KCQ-FVIX-XXXX. Doesn't look like the seal is available separately from the charge pump cover unless it is part of the 70525 overhaul seal kit.

Fluid Film.

Most of the older Briggs push mower engines had a shorting clip that was situated next to the throttle pivot that shorted the ignition module when the mower was moved from full to just past idle. Will look like an knife tip sticking up through the throttle control plate.

Looks like that vent ie check valve does protrude from the top of the tank on that mower https://www.partstree.com/parts/husqvarna-576618101/ Item 17 on this diagram also shows the grommet that it pushes into item 23...

Looks like the tank vent is popped up out of the tank grommet. And the nipple on the vent is broke off. Normally that vent would sit almost flush with the top of the tank, and the vent line would come off of it below the fender and most likely would connect to that hose in your picture...

One of my in a box engines just needed a spark plug after reassembly
