Motorized Bicycle Trouble ShootingUse this area to post problems that may arise, if you could use some help in figuring out what is wrong with your engine and what needs to be done to achieve top performance.
I have a spark, and the piston moves when I pedal with the clutch untouched. It sound like it wants to start or that the piston is moving extremely fast either way no start. I've been trying different things going on some forums. I've replaced the magneto, cdi and spark plug. Although I the fuel doesn't move on its own down to the engine the spark plug had gasoline on it. The pistons well lubricated. Also the clutch is very tight as in I move the wheel a couple of inches and the piston is on the opposite side.
