      Description

      Consistent Fuel Metering. Fuel delivery through the carburetor depends on an accurately sized main jet, making the Carburetor Main Jet a critical component for maintaining proper engine performance. Built from brass for the Zenith-Model B-Type carburetor used on 4 cylinder engines, this American-made OE-compatible reproduction restores dependable fuel metering as a direct replacement for worn or damaged originals, fitting 1928-1931 Ford Model A Models and 1928-1931 Ford Model AA Models.

      Construction and Appearance. Crafted from durable brass, this reproduction main jet is engineered to provide precise fuel metering, dependable corrosion resistance, and long-lasting durability under normal operating conditions. The raw metal finish closely reflects the appearance of the original component while allowing the accurately machined passages and threads to perform as intended. Precision manufacturing and OE-comparable specifications contribute to consistent fuel flow, reliable performance, and the quality expected from a direct replacement carburetor component. Proudly made in America, this jet reflects careful craftsmanship and authentic reproduction standards.

      Installation. Installation is designed as a direct replacement using the original carburetor assembly. Remove the existing main jet carefully to avoid damaging the threaded opening before installing the replacement component. Verify that the jet is properly seated without overtightening and inspect the carburetor for proper assembly before returning the fuel system to service. Check engine operation after installation to confirm smooth performance and proper fuel delivery.

      Application. This Carburetor Main Jet fits 1928-1931 Ford Model A Models and 1928-1931 Ford Model AA Models. Intended for Zenith-Model B-Type carburetors used on 4 cylinder engines, it helps restore accurate fuel metering, promotes smooth engine performance, and preserves the authentic operation expected during a quality restoration.
