318 stalling from idle
That is indeed a 1967 AFB 273 carb for a manual transmission without CAP. I have 4 of them. The original rods should be Carter #16-403 which are 3 step rods .069 x .065 x .058 diameters, definitely a misprint. They are a very good carb, but the choke pull off should be removed and saved in a baggie with the attaching screws since there is no linkage to the choke shaft. Or leave it and use a cap to block off where the distributor vacuum canister was on the carb. Next connect the vacuum canister on the distributor where the choke pull off hose was on the carb. Check and reset timing to at least 10 degrees before TDC. Do yourself a favor and get a 340 accelerator bracket,
Mancini Racing - Throttle Cable Bracket . I always run a choke, but not sure how with that intake manifold.
