Holley Idle mixture screws non responsive?

yes 14* initial and then once the vacuum and mechanical advances kick in at about 2000 rpm I am around 38 or so.

I start the screws at 1 1/2 turns out... but from there they do nothing either way until almost completely closed then the motor will die.

I have all the unused ports plugged.

I agree I thought I should be able to drop it on and run it.. and its been anything but that.

I keep feeling like I have a vacuum leak but I have done the intake 4 times and always get the same vacuum reading.
