Willy’s 500 CFM Gas Carb w/ Ext Adj Block

Like our basic 44120, this carb also has 1-3/8″ venturi and 1-11/16″ throttle plate. The unique feature this carb offers is our billet metering block with externally adjusting jets. This feature will give you more horsepower and the convenience of being able to make jet adjustments without disassembling the carb all in the click of the wrist.
