Proform Street Series 750 CFM Carburetor with Vacuum Secondaries and Electric Choke

Based on the highly successful Race Series carburetors, the PROFORM® street carburetor is constructed of lightweight aluminum, including provisions for a choke assembly and changeable idle air bleeds for easy, non-permanent calibration changes if n ecessary.

Fine tuning is accomplished by simply changing air bleeds, not opening up calibration restrictions with a drill bit! This dual fuel feed inlet carburetor is assembled using the PROFORM® High-Flow Carburetor Main Body, durable bil let metering blocks, aluminum fuel bowls and a high performance billet throttle base plate.
