Talk about worn camshaft lobes! That is ridiculous. As you said, how did the engine even run?

Noco battery charger has repair mode for sulfated batteries. It pulse charges from around 14 volts to 16.5 volts to burn off sulfates on lead in battery. Some other off brand chargers have this feature also. I have two chargers that will sometimes bring back a battery. Normally only works on...

Sounds like belt has been recently replaced. How good is the belt tension?

You have replaced a lot of parts. Try diagnosing the issue instead of throwing parts at it. List the problems and symptoms of the mower, then research online the possible causes of these symptoms. This focuses your efforts towards the possible solutions.

Ultrasonic cleaners work really well. I usually manually clean the jets and emulsion tube while the carburetor is cooking in the ultrasonic cleaner.

Remove a spark plug and install a piston stop, or take good nylon rope and stuff it into the spark plug hole until full. This will keep engine from turning so you can torque the PTO bolt properly.

The shop charged you $1500 to say they can’t fix it, or it would be $1500 to fix it?

Good luck with all that. Sarcasm.

Try removing the jet from the three aftermarket carburetors, and installing into the OEM Walbro, and seeing if that works. Unless the jet in the Walbro cannot be removed because the head of jet is stripped. The OEM carburetor can be ultrasonically cleaned with jet installed and it should run...

Possible causes: Belt worn and needs to be replaced. Gearbox worn and not engaging. Wheel plastic gears worn and not engaging. Cable hanging up and needs to be lubricated.

Only mowing for 20 minutes tells me you don’t have a big lawn. If it has a mulch plate on where the side discharge opening should be, remove the mulch plate. Maybe the deck baffles needed to make mulching work properly are missing or damaged. You will never be happy with the cut quality...

You can use a metal oil drain plug if you don’t want to buy another rubber extension one. The advantage the rubber extension drain has is that lessens the mess of oil. Should be a standard mower oil drain plug you can buy. You can check drain plug size with micrometer if you have one.

Unheard of that kind of hours. I have never heard of any small engine going over 1/2 that amount of hours. I am not saying it isn’t true, just that it is an exceptionally long amount of hours.

With regular maintenance and not running it low on oil, around 2000 hours. You are reaching the end of the engine’s life most likely without rebuilding it or replacing. Keep an eye on the oil and top off as needed. Kohler Command is a great engine.

It is hard to say without actually working on the trimmer. Try lubricating the throttle cable. You may need to open the throttle plastic cover up and see if anything is hanging up inside.
