4-Barrel Carburetor

The Holley 60160 is a remanufactured 4-barrel carburetor designed for specific Chevrolet and GMC truck applications. This unit has undergone a thorough remanufacturing process, including disassembly and ultra-sonic cleaning to ensure a clean foundation. A protective anti-rust dichromate finish is applied to the zinc casting for enhanced durability. This carburetor is equipped with several new ethanol-resistant components to ensure longevity and performance. These include a new accelerator pump, float, airhorn gasket, main body gasket, throttle body gasket, cluster gasket, springs, O-rings, seals, and check ball(s). Additionally, new bushings have been installed in the throttle shaft, and a new flange gasket is included for a proper seal. The carburetor is pre-set for a plug-and-play setup, with the curb idle set to ensure smooth running without being too low or too high. The fast idle adjustment is also pre-set to manage cold starts properly, ensuring the choke valve opens correctly and the idle speed drops as the engine warms up. Furthermore, the mixture idle screws are pre-set to optimize fuel economy and ensure a clean-running, efficient engine by achieving the correct air/fuel ratio.
