I am new to hobbits and tried to get a build going
New 70cc kit. New stock CDI . New mikuni 20mm round slide carb (down jetted.)
It has never been running since the build started
The problem I’m having is it will not idle for more than a few seconds then it starts to ramp up like it’s at full throttle. Throttle cable has plenty of slack. Slide is all the way down. My guess is air leak? I’ve gone through gaskets after gaskets and can’t seem to find a leak, I’ve racked my brain for weeks trying to figure this out. Any ideas why it immediately revs up that high with a new kit?
