Remove throttle plate screws and accelerator pump linkage. Remove throttle shaft. Take throttle plate (or body, if that's the case) to machine shop. Have them ream and re-bush to fit throttle shaft. Install shaft, throttle plate and screws (make sure throttle plate is "centered" in it's bore, as throttle plates are usually slightly oval). Support shaft and lightly "stake" over the screws so they don't fall out (just ask G.L.!). Attach accelerator pump linkage.
Re-install carb. on engine, start and adjust mixture when engine is warm.
Now you will have a smooth idle with no vacuum leak at the throttle shaft and no fuel leak either!!
