The term "rebuilt carburetor" means different things to different people.
Generally, there are about 3 different classes of "rebuilt" carburetors.
(1) A general mechanic disassembles into the major components (ie. airhorn, bowl, and throttle body), cleans, and installs those parts which are contained in whatever rebuilding kit he/she acquires. Often, other parts MAY (or may not) be replaced, ie. float. Generally, no machine work will be done.
(2) Commercial carburetor rebuilders which sell through local auto parts stores will group several different numbers of carburetor together, disassemble a large group of these carburetors without regard to which part came from which carburetor into the groups listed above, clean, install THEIR OWN CALIBRATION (always rich), and reassemble using bulk parts, but the same as available in most auto store kits.
(3) A carburetor specialist will completely disassemble the carburetor (completely means ALL parts will be disassembled). Each individual part will be checked for wear or other defects. Each individual part will be refinished in the original finish; and all defective parts will be replaced with the correct part, the parts will then be reassembled using about 3 times the number of parts available in the parts house kit. The word "restore" is generally used with this grade of rebuild.
Obviously, class 3 is going to be by far the most expensive, but give the best service.
Class 1 (the general mechanic) DEPENDING ON THE SKILL OF THE MECHANIC, is going to be the next best (prices will vary depending on skill and locality).
Class 2 (the commercial rebuilder) through the auto parts store, should be avoided (MY opinion, others will differ) unless no other option exists.
Most individuals, armed with a kit, and a knowledgable friend, can do a better job than class 2.
