Well, they all have some markings somewhere, and if the name isn't on
it, then a company logo is. Look it over good. You can also find a
Chilton's book that covers it at the local library. At least mine does,
anyway. Lastly, a service manual for them is sold at many places on the
internet. Get one. Either book has many, many pictures of the carbs in
various stages of breakdown, and you should be able to identify it then.
Most people did the rebuild themselves, back in the day. If you can give
it a good look over, and still can't figure it out, post any numbers you
have on it back on here. It will have something on it, somewhere.
