They should be the same/ similar above idle but not at idle. Unless you throttle plates are cracked open a long way (too far) at idle. Can you take a picture of the ports you are refering to?
Typical holley arrangement, ported above the blades, manifold on baseplate.
There in is the rub. My plates will not close enough to get the square idle restriction. I`ve tested out on the bench with a 12 volt supply and got the choke to fully open, look underneath and not square, turn full throttle, still not square. the choke steps stay on the last step unless I manually flip it off the step then low and behold there`s is my square idle port. My thinking the only solution is to remove that last choke step?
