I have a question about running the 2 Rochester 1 barrel carbs with a choke on just the rear one. I have one really good carb and one the choke butterflies and top springs are crap so I was thinking about taking all of the choke system out completely butterfly, rod, all and just using the rear one as a choke, I know not the best way but seen several done this way and it doesn't get extremely cold here. Have any of you done this and what did you do about the holes once the rod is removed?
