I have a nice new go kart and it moves a bit too well. I have a Master 196cc 6.5hp engine and a centrifugal clutch. When I start the engine the car starts moving slowly. And when I drive with my foot not on the gas pedal, the car moves on quite well. Is my clutch too sensitive or is my car too light or my gearing too low or high. Please help me, it would help a lot.
