Scott. Don't be surprised if the technician who works on your car indicates that he needs to do a full check-up of your engine other calibrations or operating condition before putting your carburetor under scrutiny.
While your engine's operating problem may be related to the carburetor you're running, there are many other 'things' that may instead be the root OR otherwise contribute to the problem. Generally, the carburetor is the last 'thing' to adjust after virtually everything else has been verified as being properly calibrated or operating. Ruling these other potential contributors out first, is the usual order before suspecting the carburetor or setting out to 'fix it'.
Your technician may begin with an engine vacuum gauge test done at normal engine operating temperature. Depending upon what that testing shows, the tech. may desire to do a compression leak-down test. He may also do an ignition system operating test with an oscilloscope. This may lead to work related to spark plug and / or spark plug wire replacement. After checking the ignition point dwell setting and the existing ignition timing setting, he may, IF equipped to do so, pull your ignition distributor to check the centrifugal advance curve and to assure proper vacuum advance operation on a distributor machine. The checking of the distributor advance curves can be accomplished with the distributor installed on the vehicle's engine, but a distributor machine is preferred if he still has one. If previously removed, after reinstalling the distributor, he may check the engine valve lash setting. Subsequently, he'll check your ignition timing setting at idle (with the vacuum line to the distributor disconnected and taped closed) and then will check the idle adjustment of the carburetor. After doing all of this other 'stuff', he may have you take him for a road test involving low speed operation, stop-and-go operation, engine operation in going up a long hill, acceleration to attain highway driving speed, performance when doing the equivalent of a vehicle pass at highway speed, and performance at consistent highway speed for a reasonable distance.
Your technician may do some other things, but the above narrative will give you an idea of what was common to do with pre-computer controlled engines that had carburetors, solid lifters, and ignition distributors with ignition points.
Hope this helps!
