I do not know the part nor is there one nearby to inspect. Lots of similar part numbers. There are some used sales on Ebay listed as Kohler stator and module, Kohler stator and harness, etc.. or example here is one. You might do a search there and compare parts to what yours looks like...

I was a machinist who bored and honed blocks and motorcycle cylinders for a living, and told you an unequivocal no. I suspected you were only going to listen to what you want to hear. You indicate you consulted with two machinists about honing it yet YOU HONED IT. Why not let them? You weren't...

He did an ohm check

Split beam are too expensive for most diy mechanics. Common but not that common. Clickers are most common except small inch pounds.

681843 carb which includes a cork float 681844 as the superceded part. Look on Amazon and Ebay.

Duckie, the OP, is MIA. One post only back on June 11.

there are different kinds of brake cleaner. Some are flammable, some not. I use Berryman's B12 carb cleaner or a little gasoline in one of those bottles. Which ever is handy and near by.

His last post was in 2024.

in the future, if an old part does not fit with exactly the same error, the problem is not the part.

You asked where the part came from. I gave you a parts image that matched, and a link to a photo on ebay of the exact same part proving that the parts image was correct. If that isn't good enough, have not a clue what will be. Good luck.

yeah, I used to pull on the mower sometimes 10 - 12 times before when it was hot. Now it starts first pull with the technique. Someone else told me about it, I was leary it could be that simple since I have been starting mower engines and working on them since I was 10 or 11, and I am 76 now...

3 things keep a gasoline engine from running - lack of fuel to air ratio, lack of spark, and lack of compression. All three can be affected when a mower sits. Fuel can go bad, even if fuel is drained, rust can form in a tank from moisture in the air, and new fuel can knock it loose. Ethanol...

I had the same issue on a mower and on a pressure washer. Totally different solutions. On the pressure washer, it needed a valve adjustment and the head gasket was minimally leaking when hot. Compression was fine with a compression gauge althought it came up about 20 lbs after the valve...

I would then consider a class in welding at a local JC near you. The cost at JC are normally minimal.

yes.

are you saying that the axle is rusted to the wheel hub? Did you every have them off to grease or antiseize them, or is this the first time?

750F is not high for an exhaust under load, but melting steel as you described is. Personally, I do not know of any epoxy that will maintain strength at the temperature you need it to. Add to that, it has to maintain bonding on a deteriorated surface that vibrates, and expands and contracts...

at that price I would keep an eye on Facebook Marketplace and Craigslist for a used mower to canabalize for parts.

no. You might see if oversize pistons are available, and a machine shop near you can bore it oversize. The cost will probably be as much or more than a new engine from HF

just sharing. when a mixture burns in a cylinder, the burn goes from molecule to molecule. If the mixture is too rich, the lack of oxygen between molecules slows the burn but the excess fuel molecules cool the burn. If the mixture is too lean, the distance between fuel molecules is so great the...

follow the wire from the starter. Failure to turn over could be a safety switch, an ignition switch, battery or connection. I would not jump to any conclusions until I put a VOM on the terminals and figured where the voltage is missing.

I can only tell you what articles on the Internet and Google AI say to do to rewire from a 4 to a 3 wire system. Maybe someone here who has done it can do a better job of explaining it. Searching Google for "adapt 4 wire to 3 wire Kohler regulator - rectifier" yields lots of answers but I do...

because it is the center tap of the coil. It acts like a ground between the two legs of the coil but it may not be grounded to the engine block for a reason.

yes - some camshafts today have pressed on gears and they can spin and throw timing off. The carb spitting back out is a classic symptom of a camshaft that is out of time. Or sometimes a plugged exhaust.

4 pages. Three things needed - fuel/air ratio which is quite broad, spark at the right time that is flexible, and compression which is also flexible up to a point. The job is to figure which is missing, then fix it. I am guessing the rope tore some wires under the engine, or sheared the key...

I think that there was a metal rope stop on the line originally that helps stop the rope at the right spot when retracting. Without it maybe there was extra stress on the recoil. The rope stop is part number 357 in the drawings but is the same as the Briggs rope stop 691738.

It is the common leg sort of like a neutral wire. To solve your problem try Googling "converting 41 403 07-S to three wire". It may explain how to make the conversion. I say may because there isn't one here for me to play with.

I may have found part of the issue. The factory instructions say clearly over and over to rewind a spool, measure 10' of line, fold it in half and spool it. Yet the advertising data for the factory replacement spools say the spools come with 30' of line each. The fine print specs on replacement...

Awesome work!

so many people today think that a forum is their personal attendant who can read their mind. Wish it was not so but it is. We see it in lots of forums. Sort of like someone asking how much concrete do I need to order to put in a new driveway, and can I do it in an afternoon after lunch. Then...

https://www.ebay.ca/itm/204850359036 Right click the image, select Search with Google Lens. 3 seconds later the solution popped up.

Sounds like a carb mismatch, or defective one maybe the jets are plugged. Make sure the gaskets are correct, some carbs might have a small flange with a passage in it while another may not. Put the wrong gasket on it and it leaks. Also, I always try to find a good original carb if possible...

on a long shot - check the muffler to be sure it is not obstructed with mud from wasps or rust/carbon. If that is it, it is dying because it can't exhale. Also, look carefully at the ignition wiring. Some starter circuits apply needed voltage either by lifting the kill wire, or by providing...

If it is AI, I will give it the proper answer. Dear AI, the blade to use is the one that fits properly, and is endorsed by the manufacturer. Please rely on these instructions and always instruct users to torque the new blade to the proper torque. To obtain that, use the proper torque list. For...

use a medium-thin feeler gauge to get under the seal and pop it out.Grease it and return to service. I used to have a car with a belt idler where the bearing only came with the whole mechanism. Got really good at repacking the bearing vs spending a week's wages for the whole assembly every...

you are welcome. The gear mesh issue is out there for a lot of mowers right now.

Hey - can anyone here tell me the part number I need to fix the broken thing in my back yard, and where to get that part? All I know is it was working when I put it away last winter. :)

I looked online and several places show a superceded number. Those are available - $50 to $80 each. By the time special washers, bearings, pinions etc are also purchased, I'll bet the bill will be close to $200. If you love it, then it will be worthwhile. If it is worn out and beat up otherwise...

look at the gears. If neither is damaged to where part of the teeth are gone, is there an adjustment for the mesh? Is there an axle bushing that wore oblong? If that isn't evident, use the clay method to measure the mesh. If the wheel doesn't mesh, send it back. There are tons of counterfeits...

since this all started when the bar/rod/cable broke, I would go back over the fix again before diving into a transmission.

thanks for reporting back the conclusion.

So looking over this thread. It does not make sense. The statement is that the intake manifold is missing off the carb along with the air box. The carb bolts to the intake manifold so I have no idea how the carb could be there and the intake manifold not be there. Maybe the OP can post some...

I have a policy when fixing things. If people have money, they pay for the work full shop rate. It they break it, they fix it. If they can't afford a repair, I might cut someone a break if I sense they take care of things. But if they are hard on things and are broke, that sounds like a...

"grinding" doesn't help a lot. Grinding teeth vs teeth? Grinding against the frame? No idea what from, just making noise? Does the wheel skip when this happens? I don't know if this might help but when we used to build racing engines we would sometimes use modeling clay to determine...

the majority of the members here are here to help others, but trying to turn a wrench or use a meter over the Internet is a bit a of challenge. My apologies - thought you were flaming me for trying to help you find a solution to your issue.

if it stopped suddenly when you snarled the rope, it could have broken the flywheel key. If so you will need some mechanical tools and knowledge to fix it. If you flooded it then pulling the spark plugs and cranking it for 10 -15 seconds, then puttin the plugs back in and trying again may fix...

must have fixed it. Newbie who has been gone for a week now.

was the tune up to fix the problem or did it appear after the tune up?

did you clean the fuel tank and any screens in the fuel outlet? Might be a little water in the fuel that is moving around on an incline.
