    Gas isn’t getting to plug

    I bought an 80cc kit three days ago. I haven’t been able to get it started. Turns out gas isn’t getting to the plug. I don’t know a lot about two strokes. How can I fix this?

    Spark plug

    So I think my spark plug malfunctioned and I got a couple different ones from auto parts store. Neither seem to work. The engine might sort of run and backfires the entire time. I just took the chain off and peddled home. Help

    Engine Trouble Losing rpm once engine gets hot

    Ive finally built a screamer (almost). When I first top out my 66cc motor from the start, I'm hitting about 8500 rpm(36mph). I have a high compression head, I've raised the exhaust and redirected the transfer ports and installed an expansion chamber. I'm running a B7HS plug. Here's the problem...
