The original issue still exists, that with both points in use, the engine stumbles just above idle, to the point that it is not even drivable. As I mentioned, if I isolate EITHER set of points, it runs normally.
I would question the integrity of your coil as blocking either set points changes the dwell and has a direct effect on the coils saturation time That appears to be the only variable IMO
You got it!
It was the coil!
I have and MSD Blaster 2 in there. I wondered about it, but with it running ok on one set of points, I couldn't exactly see how that longer saturation time would affect this type of coil, that is designed to deliver more voltage anyway.
Put a $19.99 O'Reilly coil in, and it works fine. BTW, the coil isn't bad. I put the old system back in place, and it runs normal. That coil just doesn't like the saturation time of a dual point system.
I would like to understand why this is the case though, if anyone can explain the electronics...
