When I run my engine in my garage and let it completely warm up and then go to shut it off it always ends up firing a couple more times maybe for 3-5 seconds. It is very crude combustion and only a few cylinders are firing,(so I don't think it's the ignition) but it is enough to keep it running for a couple seconds.
The only reason I'd like to fix it is because it kind of makes the engine seem like a piece of junk when I shut it off and it coughs a half a dozen times afterwards.
I haven't yet gotten the thing on the road and really gotten to heat it up good. . .is it possible that I just have some deposits I need to burn off that are igniting the mixture?
