I was  checking my throttle position switch for idle, and found it was  not
clicking when the throttle was allowed to close, but if I pulled up  the
throttle shaft, it did click on throttle close.  When the throttle  is open,
I have about 1mm of vertical play in the throttle shaft.   Excessive?  is
there an adjustment or shim to raise the throttle  shaft?  I do not detect
much axial play as if the bore in the throttle  body is worn.
Thanks as always,

Edward, most all Vanagon throttle bodies have that  play, it's how they were
built.  When I rebuild the throttle bodies, from  my _Vanagon Used Parts_
(http://members.aol.com/Fkc43/usedpts.htm)   webpage, Throttle body 1.9 or 2.1,
rebuilt, excellent better that new  condition - 250.00 exchange or 300.00, part
of the process I do is to  shim that play so that the butterfly stays dead
centre in the throat and the  valve can move freely.  I install stainless steel
shims in between the top  of the throttle body, where the seal is for the shaft
and the first linkage  piece on the shaft.  It may take a few trys at
assembly and disassembly to  get the right shims that give the proper adjustment.  If
that butterfly has  worn a groove in the bottom of the throat of the throttle
body you can fill it  with JB Weld and sand smooth, then paint with silver
engine paint.  Once  you have the butterfly set to ride dead centre it will not
ever rub on the  bottom again.  The brilliant engineer who designed that
throttle body  thought it was a good idea to use the butterfly rubbing on the
bottom of the  throat of the throttle body as the bearing surface - ha, ha - that
did not work  !!
