Carter A9-4618S 1969 Mopar 440 CBQ Quadra-Jet Carburetor

The Carter A9-4618S 1969 Mopar 440 CBQ Quadra-Jet Carburetor is a legendary piece of automotive history. November 1968 marked the beginning of the Quadra-Jet era for Mopar Muscle cars, and this carburetor was at the heart of the performance revolution.

This particular carburetor, the Carter A9-4618S, was specifically designed for use with Mopar's 375 and 426 Hemi engines. The Quadra-Jet system was a significant leap forward from the previous two-barrel carburetors, providing superior idle quality, smoother transition between idle and full power, and improved fuel economy.

The Quadra-Jet carburetor got its name due to the four different jets in each quadrant barrel that deliver fuel to the engine. These jets interact within each Quadra-Quad intake manifold to enhance fuel atomization. The result is a more complete combustion process and a notable power improvement. Additionally, power valves sprung from the accelerator pump gaskets, which opened when the throttle valves were fully opened, allowing an increased air/fuel mixture for better acceleration.

The Carter A9-4618S Quadra-Jet carburetor comes with a venturi size of 775cfm (cubic feet per minute), a vacuum secondary size of 950cfm, and a base gasket size of C775S/C950S. The carburetor also features a choke mechanism, which can be easily activated by a cable from the engine compartment. Technicians and enthusiasts often appreciate the easy accessibility of the adjustment screws located at the front of the carburetor body.

This Carter A9-4618S 1969 Mopar 440 CBQ Quadra-Jet Carburetor has the correct Mopar markings for authenticity and fits original applications. It may require a rebuild to ensure optimal performance and, upon installation, will undoubtedly bring the iconic sound and power that muscle car enthusiasts love.

Remember, working with engine components like a Quadra-Jet carburetor involves certain risks, and it's important to take the necessary precautions when dealing with fuel systems. For best results, have your rebuilt Carter A9-4618S installed by a professional mechanic or experienced DIY enthusiast.

In conclusion, the Carter A9-4618S 1969 Mopar 440 CBQ Quadra-Jet Carburetor is a highly sought-after component for anyone looking to restore or enhance their Mopar muscle car. Its legacy speaks for itself, and its advanced fuel delivery system continues to be admired by automotive enthusiasts worldwide.
