Lazy me uses one zip tie around the bar. Keeps her running while bagging. Slide the tie off and she goes to sleepy town. Oh plus you don't have to hold that stupid lever down all the time. Some mowers have 2 levers to hold down. Makes my hand cramp. So uncomfy. Officially I never circumvent...

Politely disagree. Not enough heat in my opinion. Heat is what releases the shelac varnish crud inside the carb. And a garage sale hot plate and some cleaner is way cheaper than an ultra cleaner. Use what you like.

Post it up on youtube. Link it here. That is an old mower. Probably needs an entire fuel system clean slash refresh. Meaning flush and rod out the fuel tank. Clean all the grass, bugs and leaves out of the tank. Make sure it flows with zero restriction out of the tank. Install all new fuel...

Did you test this new plug? Use another good coil. Sparky plugs are highly counterfeited especially NGK's and AC Delco's. If you bought from Scamazon or Fleabay, better test it. New doesn't mean new these days. Think what you are getting at is if you remove the KILL wire from the coil, will it...

Is it installed upside down?

Never seen it and highly doubt it was from E-10. Could be wrong though. Happens about daily LOL.

Then use a backpack blower and be amazed. When it's 105F outside, kinda want to get the job done in speedy fashion.

For the most part, the Chinese carbs have been fine for the last several years. I used to buy the cheapest listing, had issues in the past. Now I buy one that is say $10-15 bucks more than the cheapest listing. No issues since. I still go through each one looking for deficiencies. Float heigh...

640288, first hit on google. Says it replaces 640266. Or did you want a newer part number than the 640288? https://www.amazon.com/Tecumseh-640288-Carburetor-Replaces-640266/dp/B0F2HKPQKS

Meaning the incoming fuel line, impulse hose off the block and the output line to the carb inlet right? 3 hoses on the fuel pump. From what you are saying, you have a fuel delivery issue. Your filter is empty and engine shuts down. If you've cleaned the tank and outlet, installed new hoses...

Like this video? I would replace all three fuel lines. Bet one of yours has a crack in it.

No offense but start looking behind the air filter more often. Most filter housings are plastic. Most all of us over torque the screws warping the plastic. Filter material is worse and worse. Must admit, the only clean intake manifolds I've seen are on those old pulsa jet Briggs with the foam...

This is a 25 year old mower. Chance could be poor boot insulation or cracked weathered same deal. Guy will get blown out of his socks LOL. Dude, EXPECT to get shocked messing with high voltage like this. Use a grounded test light to draw the spark to the probe. Then pull the boot off with...

There was something about that Stabil 360. Yes it does a couple other things. Think it was it had less stabilizer in it than the regular formula? Something like that. I called them. Guy said use the old school formula. Always works for me.

If you have an old gas can, open top for sure, replace the spout with a new style. They have O-rings that semi-seal the can. Keeps out moisture, air, bugs, leaves and grass.

Chainsaws, trimmers and some blowers need 89 or 91. read your engine manual. Most all mowers, 87 is fine.

Never seen this. There is an end of life date on the bottle. Was your bottle expired? Only lasts like 2 years I think it is from the opening time. I run Stabil year round. Doing this for over 30 plus years. Never had an issue in the spring. Leave treated E-0 fuel in everything I own all...

Or a tow behind hydro-electric dam. Could water the grass while you mow. Think this guy is on to something.

Me 2.

Pressure test the carb needle at 7psi for 30 minutes. Your needle sounds intermittent.

Now I'm all confused.........

Don't know what to say about this??? Is the choke stuck closed? Choke even work properly?

For sure. Check those bearings while you "were" there.

Does harbor freight make a suitable replacement engine?

Now pull the carb bowl off. Turn the key on. Carb needle should allow fuel into the bowl area. Get a drip pan ready. Make sure plenty of gas runs out the carb needle and seat.

Jump on facetrash marketplace. Look for Snapper Commercial mowers. Can grab a clean one for around $350 in my area. Your great great grandchildren will be mowing with it. True side discharge, mulcher and a bagger that no other mower comes close to. Mine will suck spare change off your garage...

Unstick the rings. Clean the ring grooves in the piston. CLEAN as in hospital clean. Put it back together. Forget about the hash marks. Run the sucker at max revs all the time. Keep the oil on the full mark at EVERY mow. New rings will require honing slash bore prep. Current rings are already...

So the new fuel pumps are not working? Guessing these are OEM Kohler parts?

Rig up an aux fuel tank that is HIGHER than the carb. Just to confirm lack of fuel is the issue. Mow with it a while. Many a time fuel filters can look dry and the engine still runs. Did you pressure test the carb needle/seat at 7psi for 30 minutes? Does the needle allow fuel into the bowl area?

Where did you get these from? Scamazon or Fleabay? OEM parts????

I told you what I use. It is non hardening. As in EASY to remove NEXT TIME. Saves the next guy from cussing his brains out. Totally stunned and believe your story. Normally when I see RTV, there are tools laying all over the place trying to remove a small valve cover for example. You can, use...

I adjust valves yearly. Why? I like my equipment to start on the first pull. Also max engine performance and longevity. Only takes a few minutes.

Sealing up your muffler? That RTV requires muscle to remove. Not for me.

Sure but that flavor of juice must be dug off upon removal. With a crime scene clean-up once all the cussing is over LOL. Use what you like.

OEM carb or Chinese Scamazon slash Fleabay?

Then, the tank or a hose, maybe a filter is plugged. Do you have gas IN THE TANK? Push on the mower and make it slosh around. Five pages of help and you still have issues. Something got missed.

What about the fuel tank? Dude, start pulling hoses until you can find some gasoline. Start at the tank outlet.......... Open the gas cap. Let it flow. If you remove the gas cap, and nothing flows out of the tank, the tank is either empty or plugged on the outlet.

Remove the carb bowl screw or a drain screw if you have one. Remove the carb bowl. See if gas is coming out of the needle/seat. As in heading for the carb bowl but now the bowl is off.

Use Stabil fuel stabilizer, year round. That way next season she starts like a new mower. Use it even during mowing season. Keeps your fuel fresh. Fuel delivery issue and or dirty carb. All new parts, require, testing. No guaranty they will work. Especially from Scamazon or Fleabay. Chinese...

Your engine. Really needs the top shroud removed to clean the fins and all around the block. Read your engine manual.

As in cleaning the cooling fins on these air cooled engines.......... Amen to that.

Fuel tank spotless, like a new one? Zero restriction on the outlet? Solid fuel flow AT the carb inlet? Drain into a glass jar. Inspect for water in the bottom. Cooling fins cleaned yearly or more often? Valve clearance inspected recently as in yearly meaning every year? Strong spark once...

Might move this to the Craftsman mower section. Doesn't seem to be a Kroller issue.

Kbowey, are you still around on this forum? Haven't seen you chime in much recently. Hope you return. You are an intelligent valued member here.

Cooling fins were cleaned. Both sparks were verified. Do you have a solid fuel flow AT the carb inlet?

DId this get fixed? OP are you still around?

It's 2025 now. Can we please get color photos of parts diagrams? Too much to beg for? This Crayola stuff is nuts.

Does it look like a new front tire? Does the new tire come with flat surfaces? Is the mega mower parked for long periods of time causing a flat spot on the tire? Post a picture of said tire on here so we can SEE what you are describing.
