Idling Too High
Zach:
Is this too much light shining through? Picture makes it look worse than it is, cannot get them to seat any better. The shaft as a very miniscule amount of play, but doesn't change how they seat.

That's a lot, loosen the screws & readjust.

Any specifics tips to align them better? I gave it some effort before I took the picture but got similar results, is sanding advised, or bushings, etc. I’ll try again later tonight.

How much transfer slot is exposed under the throttle blades
when hard shut? Shouldnt be much.
Check the throttle plate gasket especially toward the front to
make sure it fits right.
Hold the throttle plate against the fuel bowl
without a gasket to make sure nothing is interfering with the fit.

I’ll check transfer slot later when I take it off the car. I sprayed quite a lot of carb cleaner around everything and got no response. But I can double check fitment too.
