THROTTLE STOP HOLLEY 4150

Adjustable throttle stop for Holley 4150 series 4 barrel racing carburetors provides a very strong and positive stop. It also prevents excessive side loading on the throttle shaft, which can easily cause the throttle shaft bores to wear out. The throttle stop is adjustable, and simply mounts to the carburetor hold-down stud. Made from rugged 1/8" steel with a clear zinc finish. Fits both 1:1 and progressive throttle linkages. Ideal for all types of racing.
