Hey guys, what b happenin? Have a Grubee 66/80 cc, fairly new engine, probably less that 50 miles, that wont start at all. Friend said that it ran for a bit, but the just quit. First thought was the problematic carbs, so replaced it with the much simpler one, that is good, (ran on another bike,) tried 3 different spark plugs, and yes, the spark is good to the plug, hand is still a little numb from the spark at the cap. Loosened the exhaust to make sure there wasn't a restriction. Good compression, but removed the head just to look, and the cylinder still has hone marks, but is showing good signs of the rings seating, it's that new. Still no start...going to check the crank seals right now, but I really don't think I'll find anything there. Any ideas??
