Help with carb id and port id.

[yodabiri]

Ok, so my neighbor was cleaning out his garage, and he was getting rid of a bunch of car stuff, and I got a carter carb in decent condition from him (I didnt really need it, but its nice to have I guess). So My question is, which carter is it and what cfm rating does it have? Also what are all the vacuum ports for? Can anybody please help me determining what is each port and what its used for? I have a holley 2300 and a demon 2 barrel, and they both have like 3 vacuum ports or so, while this carb has like 7!


Thanks in advance!

That looks remarkably like a carter YF.

Way too many ports! lol... I'll try.

A: Fuel Bowl Vent, probably went to charcoal canister.
B: Manifold Vacuum.
C: Ported Vacuum.
D: Some sort of fast-idle dashpot?
E: Not really a vacuum port, a place to suck stuff (like off top of evap canister ) into venturi
F: Manifold Vacuum
G: Ported Vacuum

Basically, You've got yourself an emissions carb. That's fine, just means you've got a lot of options!

Wouldn't one of those be the automatic transmission modulator port?

Sure, but it's still just manifold or ported vacuum.
