Seth,
With your machining capabilities, you should look into making a ecentric bell crank for your throttle,
to eliminate throttle touchyness at low speed.
Here is a past discusion, and
adampecush had one (1) made up, but never followed through to make more, in spite of
many people wanting them.
(like IJ, jdub, friggy, 92nsx, etc., etc.)

And here is a picture:
And once you have made some for your throttle, make some for the rest of us already using the Q45 or some other large throttle.
(just a pilot hole in the center? That could be opened up to fit what ever)
I'll buy one, if not 2.......
