    44-46 Blackjack butterfly's?

    Anyone have a pic or can tell if there are numbers on a 46 throttle plate? I ordered a 44 shaft rebuild kit. The plate has a 120 on it? Is this a 46 plate?

    120 means the Throttle Plate Edge has a Bevel Angle of 12.0 degrees...

    A 150 Stamp means it has a Bevel Angle of 15.0 degrees, and so forth.

    The Bevel Angles are important because they flow different and are selected depending on the number of Fuel Bypass Holes/Outlets (typicallly 3 or 4) in the Carb Throat.

    Need to match the Bevel Angle and the Throttle Plate Diameter of your Original 46 Throttle Plate.

    Ok well I have 4 of what I thought were 44 Blackjacks. But when I went to put a 44 shaft rebuild kit in one of them. The plate was too small.
