I just got my bike to work, sort of. There is something wrong with my throttle I think. I can get the engine to run but when I accelerate the engine slows down then sputters and stops. I have the choke lever down and when I disengage my engine and pull the throttle it seems to work fine. Whenever I reengage the engine and use the throttle it slows down and then stops. HELP!!! I also use 32:1 oil ratio. This is a new engine so maybe i need a higher mixture.
