Your date coding is correct. The S after the part number means it is the number for a complete carb, not an individual part. I believe the number after the S designates an engineering change.

I agree....the ****-S. Means the complete assembly number and the ****-SA means S assembly and the "A" means an engjneering revision of the origional design. Could be an emission related change or circuit revision to the fuel flow characteristics. IMO...the origional AFB design and later, the AVS design, were excellent performers, easy to tune (relatively) and a reliable long lived design. You either "love them or hate them"......
