The carbs originally came with a tag attached to one of the screws that fasten the top cover on. Many of these tags were lost during a rebuild. On some (not all) of the carbs, they stamped the last 4 or 5 digit number on the base where it attaches to the manifold. Add 700 to the beginning of a 4 digit number or 70 for a five digit number. In my case it would be 7005921. Hope this helps!
