Hello, all. I'm Tim and I was fairly active on this board about seven years ago. Then I got married and priorities changed... Anyway I'm getting back to work on my 51 and have a question about my Carter YF's. I've picked up an Offenhauser dual pot intake and have 2 YF's for it. My only concern is I have a manual choke carb with the number 966S, and an auto choke carb with the number 2101S. I've heard that the carbs must match, but...both of these carbs are "replacement" carbs for 32-62 Chevy 6's and both are SAE size 3 carbs. Will they play nice together, or do I need to try to find another to have a perfectly matched pair? TIA for the help! Hopefully I will be able to return the favor soon.
