A few notes:
* Vacuum from the port on the front driver's side of the carb only produces 8". Intake vacuum is 16.5" at the dual port near the distributor.
* timing is 10*BTDC base. with vac it's 15*, so I'm thinking it needs more vacuum. if i use the intake port, timing jumps way up. probably need to use that source and turn down the adjustable vac advance to 15* or so.
* 73/43b primary jets/rods. stock is 72/43b.

it could very well be some varnish in any one of the passages in your carb. take it apart and blast with some carb cleaner, then blow down each hole with compressed air. I am sure it'll run fine after that.
