High idle

Oh ok. Sorry about that. I have had the car a couple years now and rarely drive it. Only about 300 or so since i bought it. I need to keep a better eye on things. I will try the carb cleaner next. I have meant to do that but with work and all the other projects around here its been tough to spend sometime on her. Thanks for the info.

Hard to believe throttle shaft worn out at 22k

Me to. Im gonna do a little more research on my own here before i go that far. I just haven't spent any time on this car since i bought it. Its all original. Cap, rotor plugs wires the same since it was new and it runs so good i never bothered to do anything else.

When i had my shop i used Briggs and Stratton valve guides. Can get you number if you want

Thanks, that would be useful, especially on badly egged out bores.

Teflon bushings do work, which is why Holley and many OEM throttle bodies use bushings made from strips of teflon. The instructions I seen call for using .015 Teflon sheets to cut into strips and form into cylinders around the throttle shaft. For most worn carbs these should easily work, don't know about really badly worn ones.

The driver side tends to wear much more due to the side loading from the return spring. The passenger side rarely wears and generally does not need metal rebushing. In fact, the passenger side shaft bore is very thin casting and commonly cracks when drilled for a metal bushing. The teflon bushings require no drilling on the passenger side and only drilling the driver side to the size of the outer step bore. Plus teflon also acts as seals to help seal in vacuum which metal bushings can't do.
