Got it running like a scalded dog. Now the throttle cable broke out of the throttle handle. Cheap plastic that it hooks into inside the handle. Looking for a fix.Hi Jeff, if you can give us a little more info someone will help. Is this a new build? If so check the throttle cable, the barrel has to close all the way. Check for air leaks at the intake, this will cause it to rev without throttle. Good luck.
