Slant 6- Idle and Running

The rotor in the position shown is right where it was wired for cylinder 1 on the cap. Distributor vacuum is capped off during the timing test, though it does the same either way.

Could be my timing light I suppose. The physics of a timing situation where cylinder 1 is firing in various positions to the crank doesn't make sense for a car that idles relatively calmly at cold... and keep running when warm but choked.

I'm missing something. I can recheck my vacuum situation I guess elsewhere on the car.
