Well after singing the praises of my ching chong engine on my 15 ton splitter, it died yesterday. Went from running great to nothing. Seemed like it was electrical. I got a new plug and am only getting intermittent spark. On a saw I'd clean and check the gap with a business card between the flywheel and pickup first, but I don't know anything about 4 strokes. Suggested course of action ideas welcome.......I'll mess with it some today and if it isn't something simple, I'll hve to take it in.
