Not Ranked

Holley needs to check their calibrations, I've had 2 carbs with the primary screws 1/2-3/4 turn out, and the secondaries 2+ turns out, and know of someone else who had the same setup. Also, the last carb had the butterflies closed with no t slot showing.

BossHemi429, since you are an advertiser for the ultra hp, can you explain this?
