For some reason my 66cc 2 cycle bgf engine does a lot of 4 cycling. Can you give me some help with this. Just above 1/2 throttle with a little pull it's fine, but above and below it 4cycles. Full throttle it seems to be fine. occ stingray chopper with 44th sprocket and extended exhaust. Bottom end decent top end not great.
Thanks
