When you close off the idle screws, the motor does want to die, right? How many hurns "out" are the idle screws 1.5 turns is a good starting point for a two point idle on a holley. Try a squirt of carb cleaner into the idle bleeds.
While the car is idling, if you cover the idle bleeds, the idle mixture goes very rich.
You don't see fuel being pulled out of the boosters during idle do you? Has the idle RPM adjustement screw been turned so far as to move the throttle blades beyond the tiny slots in the baseplate?
A carb will not have ideal stoichiometry at all rpm's, you try to get as close as possible, without going lean during WOT.
