You are looking at a Carter AFB 625 CFM 4 bbl carburetor. This is an over the counter carb for Pontiac applications. ID pad is stamped 987 9635SA. It is dated C7. Nothing is frozen. All of the moving parts are free including the idle screws. Looks to be complete. Has been sitting a while. I don’t have any history. A good core for your rebuild. 

I WILL NOT USE USPS FLAT RATE BOXES.
