Thank you to all for the replies! I got several promising leads on how to
deal with the throttle shaft bushings. The only thing I am not entirely sure
of is if they actually need to be replaced yet. Since the car is not running
right now, I can not spray the carb cleaner on the shafts while it is
running to check for a vacuum leak which seems like a definitive way of
knowing if the shafts/bushings are worn. I think what I am going to do is
proceed with a rebuild on them, and if I ever get the car running :), I'll
do the vacuum leak test. I figure the carbs will need the rebuild regardless
so I'll get that done and deal with the rest later. Thanks again to
everyone!

Hello all and Brian,
I'll put on my vender hat now and say that I can rebush throttle shafts
for you. To get the directions correct assume the carbs are still on the
car. If the shafts move .001 inch toward and away from the engine and .020
toward and away from the radiator then they are in pretty good shape.
Another test is spraying some carb cleaner at the ends of the shaft while
the engine is idling. If the engine running changes then you are sucking too
much air around the end of the shafts. Also as they wear more fuel leaks out
past the bushings and you end up with crud building up around the end of the
bushing. Check out my web site at:

I am doing this as a hobby so I am a little slow some times. I am
charging $80 to rebush a pair of carbs.
If anyone is interested please email me off list.
thx,
keith williams
