Bloody Hammer, how is your Roch B working out? I noticed that you got your rebuild kit from Mike's. I just ordered mine from him. He called me and gave me a lot of time on the phone as we ascertained the precise parts that my version of the B needs. He impressed me as knowing what he talks about. He advises against doubling the gasket because it puts something out of kilter -I don't recall his reason exactly. How did you remedy your leak at the throttle shaft? New Bushing? Or did you change the throttle shaft?

My Roch B seems to be an oddball. For one thing, it has stamping on it of "BC" which should mean that it has something other than manual choke. But all I have is manual choke. Then, whoever did the last rebuild of this carb put on a main gasket that did not have a hole where the carb has a hole. Also, the sintered bronze bearing was missing. Maybe all this is why I was getting bad mpg. We shall see. I have a stock 250. How is your mpg now?
