Hei conversion troubleshooting
Ok, so in a quest to compare my working points with my not working electronic distributors, I found that the rotor phasing is very different.
At base timing only (distributor off car) the points distributor is firing (points fully open) right as the trailing edge of rotor has passed the contact.
Both electronic distributors are firing (reluctor aligned with magnet) perfectly centered up with the contact. So when I was looking at rotor phasing, thats what I was seeing... That's where i thought it was supposed to be at idle. Obviously with vacuum the rotor moves counterclockwise toward the front of the contact. But my issue is with vac advance unhooked as well.
So, the question is if the rotor phasing is off on both of these electronic distributors, how and why? The reluctor on the distributor I got from Ray is clearly installed with the roll pin next to the clockwise arrow, for small block. Really, it looks like my points distributor shouldn't be working right, but it is. I am really confused now.
Am I grasping at straws here? With vac advance unhooked the fact that the rotor tip on the electronic distributors is perfectly aligned should make them run better than the points dist. Unless this difference in phasing is totally unrelated to my original problem.
