I have a 73 with the original dual carbs (34 pdsit 2-3) that I will be rebuilding this winter. It has the typical worn throttle shaft/bushings that I am unsure what to do about. Right now I am running a little bigger idle jet so they will run a little better. Can these original carbs be saved somehow? Who can repair/rebush these carbs and actually knows what they are doing? Nobody in my neighborhood has any experience with this and I don't want my engine to be someone's trial and error subject.
I have a used set of carbs(Solex H 32-34 pdsi-3)that have no play in the throttle shaft. Will any parts from these carbs be useful in rebuilding the original pdsit carbs? Thanks in advance for any suggestions.

COrrect if I'm wrong folks, but I'm pretty sure the throttle shaft plates are removeable with two screws . I think I found the plate with the throttle shaft and swapped them from a different carb, like a Beetle 34 PIDST .... I can't remember. Any decent carb shop should be able to rebush that. Take the throttle plate in though. A lot of carb shops don't visualize much when you say old VW and stuff like that ( in my experience ). Taking it in will show them how easy it is .......

Yeah, its an out-dated art-form, but my Dad showed me how he did it for decades on all manner and type of carbs. We took a pair of 34ICT Webers with horrible throttle slop...then with shaft removed, set em up in a rig on the lathe, widened the bore on the throttle shaft holes (very carefully). Then we used the lathe to cut a brass sleeve to exact outer and inner dimensions, and carefully shoved the sleeve in to the bore.
At first the throttle shaft is quite tight, but working it in with mild abrasive(Brasso)...you end up with excellent throttle shaft movement. Requires a steady hand and a good lathe and lots of spare time !
If you cant find anyone to do it up that way, let me know...my dad might be able to dialup those PSITs
