I believe I have found a vacuum leak in my Autolite 4300 carb. Both of the throttle shafts appear to be the source. Anyone have an idea on how to seal these leaks? I've had this carb apart at least 6 times and the throttle shafts are a little bit loose in the carb body.

try your local auto machine shop--the thin bronze valve guide liners work great for this fix

The doc's suggestion is a good one.
