My Pro-billet MSD distributor was phased between two of the towers. I used their phasing kit to dial it back to a single tower. The motor still did not start on the first crank most of the time. It sounded like it had too much initial on the first crank, and then would fire right up.
Later, I read that MSD inadvertently swapped wire colors for the pick-up lead on a bunch of their Pro-billet dizzy's. I popped the wires out of the plastic coupler and reversed them. Once I did this, I no longer needed the adjustable phasing kit.
