Holley 4412 Carburetor Addendum
7/30/14

Holley 4412 2 barrel carburetors are no longer required to have the screws protruding thru the throttle shaft a minimum of .060 inch. Holley has changed these screws to stainless steel screws which are loc-tited in and are flush with the shaft. This applies to all classes using the Holley 4412 carburetor.

Note: In the V-8 Warrior class, carburetors must remain stock. The QuadraJet carburetors have never had the screws flush, so they will still be required to have the butterfly screws protruding a minimum of .060 inches thru the throttle shaft.
