Billet Microswitch Bracket Kit - 4150 & 4150HP Carburetor Flange. Tired of tinkering with your microswitch bracket to get the proper adjustment? NOS has just released 2 new part numbers to remedy this. Made from laser engraved, black anodized aluminum, these brackets are superior to any other brackets on the market.. NOTE: The 16512NOS Microswitch Bracket requires the choke to be permanently removed for installation. If you require a choke or have a vacuum secondary 4150 such as a Street Avenger, the 16513NOS 4160 Microswitch Bracket should be used.
