Just got one 562xp x torq in yesterday, guess gotta start someplace,- doesnt idle and lack of power and when I took the spark plug out it was white - a little lean I would say, the only good news is it has pretty good compression and no scores on the exhaust side of piston but another known issue is the ring pin going a missing allowing the ring to do whatever it feels like but don't really want to get into that yet, love learning but this one ... hmmmm.... makes ya wonder why they couldn't just leave well enough alone with the hands on carb.
