WICruiser,
I'm still using the original style Rochester single barrel with automatic choke. It was original style equipment for the 1961 engine, although this carb is a replacement. I do, however, have two different Carter 1 barrel carbs in the basement. One is a yf 3211 with automatic choke and the other is a yf 2100 with manual choke. Both would require a rebuild, neither looks like it has ever seen any use.
