It might have four hoses?
Pcv and Brake booster go to separate large ports, the pcv usually to the carb base and the booster to the manifold fitting.
Vacuum advance goes to one of two small ports on the carb. Test to find the one that has no vac at idle but as soon as you touch the throttle you get vacuum.
Cruise goes to either the small port on the intake or the carb base. It could be split off the vacuum advance.
i need vacuum diagram for a carter abf competition 8867
Its a Carter Thermoquad. Essentially, its a 3 pc. 4 bbl Carter with the top plate/bottom plate made from metal like a reg. carb but the center section is made from Thermo plastic..thus the Thermoquad name.
750
Never heard of this carburetor.
750 CFM
no advantahe at all stick with the original
Yes, same block, same basic engine. I have a 273 with 318 heads on it, and a 2 barrel Holley, but the Carter BBD was stock.
It depends, if you get the exact same carburetor, then no, but if say you upgrade from a single barrel carter to a 4 barrel edelbrock then yes, but if you already have a 4-barrel carb and manifold then you may need a adapter which is inexpensive, but you could also get lucky and it may bolt right up.
Carburetors are fairly simple parts to rebuild, therefore going out and spending over 150.00 is not something I would recommend. The only way I would actually replace one is if one of the sections is warped and leaking fuel, or the carburetor has caught fire. Rebuild kits usually cost between 20.00 and 75.00. If you are having an issue with fuel delivery, inside the carburetor. You may look at replacing the accelerator plump diaphragm or the blowout valve on the carburetor, also the fuel filter. If you have a Carter, or a Chrysler Carburetor, the accelerator pump is internal, just rebuild it. Thank You Good Question,
I would say a 500 CFM but no bigger than a 600 CFM. I don't know if you are looking for an answer on flow (CFM) or just a generic answer like "two barrel" or "four barrel". As I recall, in 1963 the 283 was only offered with a two barrel carburetor. I believe the rated horsepower was 195. The carburetor was either a Rochester or a Carter. Flow was likely not more than 400CFM.
Float leval wrong are bad floats. Low fuel pressure, stoped up fuel filter. May not have gotten the carburetor clean enough. IT is running to lean.
Screw the all the way in,light snug, then back then out 2 1/2 turns,Fine tune from there,For best idle.If you can't get it to idle smooth,You may have to Overhaul carb.
