Im trying to do the timing on my truck. I know its right when i put cap back on distributor, but when i try to start nothing. The distributor is only going around half as fast as engine. When i put at tdc and get distributor right then turn back to tdc with cap of the rotor only moves half way around. Is this how its supposed to be ?? Help???!!??

Well.. year, make model and engine size would be helpful, but yes, the distributor spins at half crankshaft speed. If you turn the crankshaft around twice your distributor should end up where you set it.
