    Are there any numbers on the base of the carb underneath the ground wire?

    Carter AFB Selection and Tuning Guidlines:
    http://www.federal-mogul.com/fmeconn...loads/1601.pdf

    Carter AFB Tuning Manual:
    http://www.federal-mogul.com/fmeconn...loads/1602.pdf

    From Google: The 4760 is the carburetor to use if one requires a single 750 CFM 4-barrel AFB.

    The 4762 is a "companion" unit with no choke for those wishing to put (2) 750 CFM 4-barrels as an in-line dual quad with progressive linkage (rear carb primary, front carb secondary). The 4762 has no choke.

    Other units in the "competition series" AFB line are:

    4758 500 CFM with manual choke
    4759 625 CFM with manual choke
    4761 500 CFM with no choke

    For some reason, there was not a 625 no choke version.

    Also from Google:
    Be aware that these carburetors are calibrated for Chevrolet engines (low torque, high RPM). If you are placing them on a Buick, you will need to change the metering rods, and secondary air valves (possibly the idle tubes) for a really good setup. The metering rods have too great a difference from the high vacuum to the low vacuum step and will result in incorrect mixture at either the high vacuum or low vacuum (or both) conditions. The attack angle of the secondary air valve is too aggressive for a high torque engine, and will normally result in a momentary hesitation in the transission from primary to WOT. The idle tubes may not permit sufficient idle mixture for a good idle on the high torque engine

    anyone think maybe it is the torque convertor, maybe i need a higher stall one.

    A 9635 is a 625 CFM carb. These can be identified as Carter or Federal Mogul by looking at the suffix following the number. For these three numbers, the Carter will be an "S" while the Federal Mogul will be an "SA".

    Soooooo yours is a SA so it was made by Federal Mogul. Your converter is not at fault. You need to either understand how to tune an AFB or find someone who knows.....a big pain.

    Did this carb EVER run correctly on this engine?
