One of the carbs has a broken idle adjust screw in the throttle body that is not fixable. The setup is for a 216 that I’m putting on a 235. I have read that I need to use matched carbs and these Rochester’s are in nice shape for a rebuild. What makes them matched? Can I just change the throttle body? The # on the base of the throttle body reads 7004522c on both carbs. I’m guessing that I need to find that same # of throttle body. Carb body reads RF Rochester GM | | |
