Moroso 4150 Style 4BBL Racing Carburetor Throttle Stop

This throttle stop from Moroso is made from solid steel, giving it the strength to hold your carburetor's throttle plates steady. It's designed for 4-barrel carburetors that mimic the popular 4150 style, commonly found in performance applications where precise idle control is important. The steel construction means it won't bend or deform under pressure, ensuring a reliable stop for your throttle linkage.

When you're setting up a performance carburetor, getting the idle speed just right can make a big difference in how the engine behaves off the line and at low RPMs. This throttle stop helps you lock in that perfect idle setting, preventing the throttle plates from closing too far and causing the engine to stall or run erratically. It's a straightforward piece that does exactly what it's supposed to do: provide a consistent mechanical stop for your throttle linkage.
