That's what I was afraid of.

I agree.

I tired this and I also looked into the throttle throat when I manipulate
the throttle.  Since the shaft moves in and out (ie in a parallel direction
as the shaft) the butterfly valve catches on side of the throttle body
intake.  I don't see any wear marks in the thottle body, except wear the
valve has been hitting the side.  If you push the shaft to the right (when
looking at the engine from the rear) it will fully close.  I was thinking
since the spring puts some bias to "pull it out" of the throttle body this
is why it's inconsistinent.  Is there something to tighten to keep the shaft
from pulling out?  What keeps the thottle valve shaft in the right location
in the throttle body?
