Proform 850 CFM Street Series Carburetor With Mechanical Secondary, and Manual Choke
Based on the wildly successful Race Series carburetors the new Proform street carburetors are constructed of light weight aluminum, and changeable idle air bleeds for easy non-permanent calibration changes if needed. Keep your drills in your tool box; fine tuning is accomplished by simply changing air bleeds not opening calibration restrictions with a drill bit.
