the flats inside the nut will no longer have contact on the flats on the needle
and it will no longer be able to adjust the needle in and out of the bowl.
If this happens remove the gasket from the Nut and it may then be able
to once again contact the flats on the needle and back it out of the bowl.
 
Beyond that sometimes the Float Arm needs tweaked to midrange the
needle and seat adjustment in the tapped hole in the bowl
but that is seldom the case.
Did you adjusted it as per PHAT post, the nut is used for the adjustment the screw is a jam or lock. Also as he said maybe the tang on the float needs to be tweaked? I would turn the bowl & float assy. upside down to see if the adjustments do any thing.
I have never had a float adjustment not work on a Holley carb.

O.K., I'm dumb. I simply didn't have the adjustment screw backed off enough. That's what I get for trying to do this while keeping an eye on my 2 kids playing in the front yard. Once the 4 yr old is done with his nap I'll try to fire it up.

YeeeHaww!!!!  I think we're back in business!  She ran at idle (750rpm) for about 5 minutes, gas level in the sight glass was about 1/3.  Thank you guys!!!!  Could not have done it without yours or my brother Tony's help.  (Yeah, I know there's an exhaust leak....Confused)
