What I've done for friends a couple of times is shorten the check needle that's under the screw up so it gave me a few threads for the screw to bite and it worked okay. A lot of Ford holleys on 460 trucks have a check needle that's only about half the length of the standard needle and they work fine. They are also aluminum so loosing the weight won't keep it from seating . Just a thought.

It's purpose is to seat when you let off the throttle to make the accelerator pump cavity pull gas from the bowl to refill the cavity with gas instead of pulling air back through the squirter into the pump cavity, which it will do. I've seen guy's scratching their heads when they left it out.
