The marks have been off for a bit. Checked this morning with distributor rotor pointing at number one plug wire as a quick check. The factory timing grove is still out of site at that point, right near the bottom of the balancer.
I think it has been like that ever since I rebuilt the motor a few years back (46k miles since). The machine shop put the balancer on; could they of put it on wrong, or incorrectly clocked?
As mentioned, the harmonics (not really vibration) has been taking place for the past 1200-1300 miles.
