Details

Throttle stops are fairly simple devices. A quick add-on to most 4150 style Holley/Demon carburetors, that helps prevent the throttle linkage/butterfly from overextending and sticking - preventing a scary WOT situation out on the racetrack or even rumbling down the highway. Throttle stops also can prevent the throttle from sticking in the "closed" position, preventing a successful pass or stalling out in the corner.

This throttle stop will fit most 4150 style Holley and Demon carbs and may fit others with modifications. Mounts directly to your carburetor's base plate, near the linkage assembly.
