I have 2 Carter carbs and 2 strip kits for sale.The carbs are both numbered 3721 sa. One with manual choke has d4 under the 3721sa number. Other has k4 under the 3721sa number. I ran the carb with the choke for years on a 283 sbc.The other i bought and have not run.it was painted gold by previous owner(no clue why) Both carbs will need kits im sure. I bought second carb to use on tunnel ram but went with holleys.The strip kits I bought used but look to be pretty complete.Please note where fuel inlets are on carbs.one on front left corner and the other on back left corner. The carb without choke assembly may need a heli coil for vac. advance port. If you have ?s please pm. Asking 300 for all plus the ride.
