Case used two different carburetors during the 630 production run.
Zenith - 0-12534
Marvel Schebler - TSX-799
In my opinion, the easiest and best route if your wallet will stand it is to buy a new Zenith replacement. I believe the current number 14996 is the correct replacement. It can be had for around $250.
I've attempted to rebuild several old carburetors, and sent several out for rebuild. In nearly all cases, they simply don't work well for me. As an example, I rebuilt a MS TSX-635, then replaced it with two other "professionally" re-built units. In all cases the tractor ran terribly. There was no way to get it set properly. Finally I installed a new replacement Zenith and the tractor starts and runs like a top. My experience has been similar on several other 40-60 year old tractors. Many of these old cores have been re-built numerous times and are junk.
Your milage may vary.....
