<VV> New throttle shaft or...

[Geoffrey Johnson]

I have done at least 2 dozen.   Really pretty simple.   Just size the 
screwdriver right, and be careful with the brass screws.   Almost all of 
the wear is on the shaft usually.   Not that the body does not, but  
usually not bad, and a new shaft   helps a lot.

I say that because even with the help of a spring installed, it does not COMPLETELY return to idle. (I've tried various strength springs). The linkage is good/tight and has tie rod end bearings.
