Thought I had it fixed. Ready to pull the last hair out of my head! Son took it out, and after 10-15 minutes of riding, it does the same thing. Put in new plug, same thing! Done tearing my hair out. Took it to a real small engine mech. and he has had it sitting there all week, hasn't touched it yet. Gonna go pick it up. When it cuts out, it has spark. I put a timing light on it just to see if it was the spark cutting. Seems to be gas related, but everything is absolutely spotless, and when I pull the gas line, it flows plenty good. It has plenty of power, so compression should be fine. Little sucker will pull the front wheels off the ground with 195 lbs on it, me.
