I think I may have a bad one. It only gets spark when it wants to. Everything has been double checked... I've heard they can be bad. Any one else having probs?

Yeah mine wont run past 1k rpm for some reason, but if I bypass the box, the motor runs fine.

Ive been running mine with no problems. Locked out ignition though with a pro blaster 2 coil to a pro billit distributor.
