Another carb help...

Kalums,
>>I pulled the cap my rotor was point almost directly at the carb, NOT towards cylinder #1. <<
The rotor should point to the distributor cap tower that the #1 plug wire plugs into. It has nothing to do with the location of any cylinder, just the location of the plug wire in the cap.

Dashman,
>>Timed port vacuum is NOT a failed emission thing. That's a myth, fallacy, propaganda... <<

True. and in fact the exact opposite is true. Carburetors were not modified to include 1/8' vacuum ports for any purpose associated with ignition timing until the late '60s when emission systems were developed.

The first carb pictured is a early '60s Carter AFB. It has the small 4" air cleaner flange. There is no manifold vacuum port. There isn't even a casting bulge for one. Notice the ported vacuum fitting. Early '60s and before used steel line with threaded fittings for distributor vacuum.

The second, I believe to be a '69 Carter. The rubber vent valve is on the outside, connected to the pump arm. The vent valve was moved inside the bulge on the top, passenger side for the '70 carb. A 3/8" vent tube exited that bulge at a downward angle and was connected to a charcoal cannister. It has a 5" air cleaner horn and most noticeable is, NO manifold vacuum port or even a casting bulge for it.
I have two '69 AVS carbs. I also have a '70 and a '71 AVS that do have the EVAP port, but not one of the four have a casting provision for a manifold vacuum port for the ignition.

The third picture was said to be '67 Quadrajet. Ported vacuum, driver side of the main casting, but something is missing. Oh ya. no fricken manifold vacuum port for the distributor. I've seen many pictures of early (65-67) Quadrajets with no manifold vacuum port for a distributor, but in '67 Rochester carbs started growing crazy numbers of ports for every kind of emission systems GM could think of.
