could or the breather could be plugged or head gasket leaking combustion into the oil passage.

based on the choking, unless there is residual water, which I doubt based on your attention to detail, it is probably something like a valve wobbling around, or perhaps a bad plug or wire. If a new known good plug doesn't solve it, the only thing I can think of is maybe widen or narrow the spark...

A lean misfire can be a mixture that is right on the edge of being lean so any deviation leaner can cause a random misfire. I'd use the choke or my hands to richen the mixture and see if anything changes. That and the new plug will pretty much eliminate fuel and ignition as a source of the misfire.

try replacing it with a known good used spark plug since the guy put his own in, unless he will pay for a new one. There are so many counterfeits out there now it is unreal. They can check fine out of the engine, but under compression they can fail. The problem sounds like a lean misfire. and...

if it is two cycle don't forget the oil if it uses a 2 cycle mix.

check the oil level, and for gas in the oil

wiring replacement after a fire or overcurrent melt is about the worst job out there. I excel at finding and fixing electrical and electronic problems, however when I was a mechanic that is one job I always turned down. Guys would take it, then spend a week or more fixing wires, and the...

I usually use a loop of wire around any spring that I can't pull with vise grips or some kind of spring puller like auto drum brakes take.

Unless the spark plug was from a known good source, I'd try another. Then I would blow the cylinder out with compressed air to dry it. put a thimble full of fuel in it, and try again to see what it does.

FYI - regular simple green will dissolve some carbs. The HD Metal Safe version doesn't do that. Home Depot is the easiest place to get it. Our local Lowes did not have it the last few times I looked for it there.

there was a youtube on it recently. The new caps lack the hole. It has to be in a certain spot to stop gas from sloshing out. Starts about 5 minutes

set it into the fluid in a way that the air can get out. Use "Simple Green Pro HD SAFE FOR METALS" with hot water and you will get metal safe results. I spent considerable time finding something that is 100% safe 100% of the time for aluminum and carb metal. Everything else has potential to...

most lead acid batteries are degraded enough by 4 years to replace them. Some people consider 50 - 60% life left good. Others replace them at that point. Some consider them good until they don't work. The next door neighbor has a Toro recycler with electric start. His only charges when the...

did you check the three lines to be sure they are on the correct nipple?
