Re: I can not get my 80cc Motorized bike rinning correct.
You are too rich, I'll bet money on it. A new carb will not fix the problem. Look around the forum, use the search bar, and look for tuning info. Jetting is simple, all you need is the jet, solder and micro drills.
In the future, proper spelling and grammar goes a long way toward communication. Also, the more information you give the better.
How many miles on your motor? Check for leaks, intake exhaust, head, jug and case. When you have no leaks, your rings are seated, and you're still fourstroking, rejet, smaller.
