Is there a small engine area on this forum? I.e. 2 strokes, weedeaters, chainsaws...etc?

Well, I think I screwed up..

I'm just looking for things 2 stroke. Kinda stay away from the mowers..

Go to the home tab at the top of the page, click on it and the drop down will show many 2 stroke brands and forums.

Excess carbon in the combustion chamber or the muffler was coked up with carbon deposits.

That wasn't either. I actually did a decarbonization on it which didn't resolve the problem. BTW none of the local Stihl can even get the decarbonation fluid so going there you are SOL most times.

That is something I have been running into lately on both Stihl and Echo 2 cycles where carbon is locking up the cylinders. And spark arresters have always been a problem area so they get pulled and clean if needed on every unit.

Ask. I'm an old two stroke guy.

Here is question for you then. Have you had one to diesel that even the Stihl trained tech couldn't repair? And BTW the unit idles normally.

Possibly wrong flywheel or wrong rod? or simpley running too fast when shut down, too much momentum

Oh well no one knows what caused the problem but I do. I glad I charge to customer $100 to fix it and $95 of that is profit.

Only other thing if not carbon would be a piece of head gasket not machined correctly, sticking into the combustion chamber and glowing red.

Actually one more thing. Wrong type of spark plug with the wrong heat range. If a projected resistor plug were to get hot enough it could definitely cause this.
