['64 High Idle Problem]

Does anybody know how to solve a high idle problem on a ’64 Avanti R2?  The problem is best described as the engine idles (above 1000 rpm) unless I rapidly depress and release the throttle pedal (kicking down the idle).  It is not due to the engine being cold and the throttle being on the fast idle cam.  It occurs whether the engine is hot or cold.  It is not due to the dashpot either.

It is also not the carburetor as I have switched to a different carb and it exhibits the same behavior.   The only thing (at least in my mind) that could be causing it is either the throttle linkage is sticking or the throttle return springs are too weak.  I tried moving the linkage at the carb and it appears to move freely and is not binding and the return springs I purchased from a reliable vendor so I am assuming they are the correct ones.

I am getting tired of kicking down the throttle at stop lights.

Any thoughts?  My thanks in advance and any help or advice is appreciated.

[Avanti hard to get out of reverse]

I need help.  I have a Borg Warner T-10,  4-speed in my Avanti.  Recently I noticed that, after trying to back the car out of my garage, that the transmission will not shift out of reverse gear.  After working the shifter and the clutch I was able to get it functioning correctly again.  The car has done this twice so far.  I am afraid to take it anywhere because of this problem.  Has anyone else had this problem and/or can you recommend a fix?  I am assuming that it is not in the transmission itself because when I crawled under the car I could put it back into neutral by pulling back on the reverse rod (after disconnecting the reverse rod from the shifter).  The rod moved very easily so I know there is no binding there.  I am assuming that the problem in the shift mechanism, perhaps with one of the (as the Studebaker parts manual calls them, “Plates” which are of different thicknesses.  The plates (I think) serve to determine which shift rod is activated serving like an interlock of sorts.  The service manual talks about adjusting the length of the rods but nothing (that I can see) talks about how to select the proper “plate” width. 

 

Any advice, suggestions?  I would like to get the car back on the road again soon.

 

Thank you for any help you can give.
