• 500 CFM 2BBL Carburetor featuring a 1-3/8 inch Venturi and 1-11/16 inch Throttle Bores. Engineered with Straight-Leg Boosters and a 50cc Accelerator Pump for consistent fuel delivery. Features a Center-Hung Float and Dual Metering Block for mechanical stability under varied operating angles.
• Address internal mechanical wear and inconsistent fuel-air mixing caused by aged factory units. This 500 CFM manual choke assembly restores factory throttle characteristics and idle stability. Specifically designed to address mechanical play in the throttle shaft during high-mileage operation.
• Constructed from pressure-die-cast aluminum with a treated surface for industrial engine bay exposure. Features stainless steel shafts and PTFE bushings to maintain mechanical alignment. The fuel inlet is precision-threaded to 7/8-20 to ensure integrated sealing with standard fuel lines.
• This manual-choke unit is intended for non-emissions controlled vehicles or street applications where a 500 CFM 2-barrel is permitted. Professional mechanical synchronization of idle mixture and curb idle is required post-installation. Includes base gasket; additional linkage brackets may be necessary for universal swaps.
