The mini bike was sitting in my basement for about 2 years. Before that, the thing ran flawless. I went to start it earlier this year and was having trouble. Turns out it was the blown headgasket which I replaced, but I before I figured out it was the gasket I was tweaking with the carb. When the bike is running and you go wide open the governer does not kick in. I feel it is something either in the carb that needs adjusting/governer/or throttle linkage. I feel this is an easy fix but do not have the TIME!!
