Re: Christian-- throttle stick solution?

I would actually like to add my own throttle question about a car I 
was working on this past weekend. The owner had recently had the 
throttle body cleaned out, and it was working nicely. We put it back 
on the car, and hooked it up to the throttle spool. Wasn't quite 
making contact with the full throttle switch, so I adjusted the pedal 
stop bolt in the pedalbox to allow more movement (second car I've 
actually had to do that on), then adjusted the spool accordingly. 
Everything seemed all good, throttle would travel fully, make contact 
with both idle and enrichment microswitches, and the whole 
assembly moved very freely. Once we got the car running, we tested 
the gas pedal, but it was like somebody was playing a prank on us and 
pinching the line as it returned. The throttle would simply not fully 
return on its own. The engine usually ended up resting around 2-3k 
RPM. When manually pushing it back closed, it would be noticably 
stiff. When disconnecting the link rod from the spool, the throttle 
body again moved freely and perfectly, as did the throttle spool. But 
when putting the two back together, it just wasn't working again. (and 
the link pins for the rod were lubricated, however were not all that 
"greasy", it was more like WD40) I managed to temporarily fix it so 
the engine would relax a little better on its own, I did this by 
reducing the length of the connecting rod. This allows the throttle 
body to pull back on the spool a litte better, but results in lost 
movement of the throttle plates. It would be nice to regain this 
movment in the throttle so the car can truely go "wide open". What 
could be causing the hangup? My only thought would be the runny 
lubrication on the link rod, but with two springs at force attempting 
to pull the throttle back, I dont see why even dry links wouldn't 
work. Whatever thoughts are out there, just shoot them this way.
