Idling Issues - Holley Carburetor

does the carb have holes drilled in the throttle plates?
does the carb have the screw down the hole for the air cleaner stud like the demons??

i would adjust the throttle plates so that the primary blades make the transfer slot look square, .020" showing, then adjust the seoncdaries so that you can just barely see some light if you hold the carb up and look down the venturi's.
