I have most or all (I can't remember) of the spec/rebuild sheets for Carter YFs produced as replacements for 1962 and older Chevrolet sixes. I also have 4 big Carter books with other makes, but I haven't cataloged what I have in those. If you can provide the model number of your carb (should be stamped on that vertical spine on the outside of the venturi), I can share with you a scan of the spec sheet if it's Chevrolet, and hunt for a sheet in my books if it's for a different make, and share that if I have it. The spec sheets have part numbers for a lot of the internal bits, so you can see if you have, for example, a 964S carb with parts swapped from a 2100S carb.
