Pro Flo 4 Timing

I set the distributor at the #1 plug wire on the cap which I had marked on the body of the distributor with the damper set at 12*. Even if the damper had been at 0* the rotor would have been very close. Trying to move the gear on the cam one tooth either way would have been noticeably off. I have two engines, one with ProFlo4 and one with ProFlo3 and both act identical when it comes to this issue.

I don’t think all of us have mis installed the distributor.
