LOL. I think the world would be a better place if I stay away from motors. All I know is this. I bought a 1968 C-10 pick-up Truck about 2 months ago. And it ran good. After many improments it runs bad and smokes. Does anyone need any help with thier car.LOL. I guess I,ll time it by ear. Trun Dis. untill it runs the fastest and smothest and still will crank okay. Does that sound right? Also, could low timimg cause the motor to have white smoke? Also does anyone know how to build a good but kicken machine. John.
