Hey, new here, I've had the bike since Feb. and constantly have strange problems. It's the GT7 model, before it was a bad cdi problem, no spark, fixed that great spark, nothing, dry plug, so I take the top end apart, snapped bottom ring was the problem, no scoring or other problems. New rings, new gaskets, cleaned everything up, new tank, but still plug is dry, verified gas in carb, on Reed valves, and past. Take apart again and there is gas in the crankcase, new gas, cause I sprayed starting fluid in carb. I don't see how it's not getting to the intake tubes on sides, there not wet, nor is the top of the piston, great compression, I'm on a steep hill and it stops me easily towards the bottom without brakes applied, any ideas?
