It is obvious,that I have too much compression on a bgf 80cc.I can't pull start it at all and the pull start is installed correctly.I also put a thicker head gasket on it,which is twice as thick as a stock head gasket.I can get it started by pedal starting it,but I have to get going pretty fast.I'm just wondering if it will get easier to start as it goes along still in break? Yes in hasn't been 50 miles on it yet.Another thing is with too much compression will it cause any damage to the motor?
