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
