You are not mistaken they were made by Rochester.
If the carb has a ton of miles on it you would probably be bettter off getting a new carb. The throttle shaft and bushings wear with miles and need to be fixed which is not something most shops can do. So you end up putting a carb rebuild kit in it only to find it still runs poorly. There are shops that specialize in carb rebuilds that can do the work right. Google will point the way.
