Established in 1985, Willy’s Carburetor manufactures high performance carburetors for racing engines. Willy’s Carb and Dyno Shop produces custom 4- and 2-barrel carburetors for circle track and drag racing applications. They offer carbs in gas, alcohol, and ethanol configurations, as well as a full line of related components such as restrictor plates, spacers, fuel pumps, and regulators. Each of our Willy’s Carb carburetors are built by hand, from start to finish and EVERY carburetor goes across the dyno and tuned before it ships. This means when your carburetor arrives to you, you can bolt it on and go to the track.
