The Edelbrock Weber 1403 Performer Series 500 CFM Electric Starter Carburetor is a precisely tuned, quality-built carburetor designed to withstand the rigors of daily driving while delivering consistent, reliable performance on the road day after day. Several features make the 1403 Performer Series 500 CFM Carburetor with Electric Throttle an outstanding road runner. The first feature is that metering rods are used to transition between circuits. The carburetor is not affected by engine backfiring, meaning no power valves to blow out and rods can be replaced in seconds without having to remove the carburetor or drain fuel. Second, the carburetor has the unique ability to “hold the setting,” meaning once it is adjusted, the carburetor stays adjusted. What this means for you is that compared.
