I recently bought a Autolite 1100 carb (PN#C3OF-9510-A), which according to the Manual I have, was used on a 1963 170cid engine w/ standard transmission. I have some notes from a different website that says that in 1963 the 1100/1101 1 barrel carb had 3 different teflon type insert/venturi sizes. They were a 1.0" insert/venturi for the 144ci engine, a 1.10" insert/venturi for the 170ci, and a 1.20" insert/venturi for the 200ci engine. By the way I have a 66' - 200ci engine w/ manual transmission.
I have a couple of questions concerning the carb above that apparently was designed for use on a 170ci engine. #1. Will it make that much difference using a carb that has a venturi sized for a 170ci engine on a 200ci engine??? How significant would the difference be in performance using the smaller venturi carb insert (designed for the 170) on a 200ci engine??? #2 Could the teflon/plastic insert somehow be enlarged (say by wet sandpaper for instance) in opening the insert to the spec opening of 1.20" used on the 200ci engine??? I hope I made sense with my questions. Thanks for any input! Jim
