Hi everyone,
I just bought a stump grinder with a Honda GX620 engine and it smokes a lot from of the exhaust when I use it and it has trouble starting after I stop it. There is oil residue in the carb and the plugs were covered with carbon when I removed them (I'm surprised they still worked). I ordered new head gaskets, but they both appear to be fine. Is it possible the rings are worn? If so, what is the best method for testing them? Does anyone have experience with this engine or ideas of what I should be looking for?
Thanks!
