Review ROCHESTER Chevrolet Pickup Quadrajet Carburetor Federal Emissions fits 1985–1986

The Rochester Quadrajet carburetor model number 17085215 is a fuel delivery system designed for specific use on 1985 and 1986 Chevrolet applications that were subject to Federal Emissions regulations. This carburetor is a four-barrel, throttle body design that utilizes a Quadjet pulse-line secondary system for improved air/fuel mixture efficiency.

The Quadjet carburetor features four separate barrels, each with an individual float bowl, delivering fuel efficiently to each cylinder in the engine. The secondary round bowls located on the rear of each barrel are fed by small "quicksville" venturi tubes which have pulse air from the intake manifold injected to create a vacuum effect during throttle opening. The secondary jets located in the quicksvilles spray fuel onto the secondary metering rods, which meter the fuel to the main jets as excess vacuum is created from the throttle opening. This design ensures proper fuel mixture under all engine operating conditions, contributing to improved combustion efficiency and overall engine performance.

The Honda Quadrajet carburetor also has an electric choke system that engages when the ignition key is turned to the "ON" position. When the choke is activated, a vacuum controlled solenoid opens the choke plate, allowing a richer fuel mixture to flow into the engine for easier starting. A manually operated choke lever is also available for short term use or for vehicles equipped without an electric choke, ensuring hassle-free cold starting.

Additionally, the Quadjet carburetor comes equipped with various air metering options that cater to various altitude and temperature applications. The use of aquastat and manifold absolute pressure sensors assists in the regulation of engine coolant temperature and vacuum, respectively, for optimal engine performance and regulation.

The Quadjet 17085215 from Rochester is also manufactured to high quality standards with corrosion-resistant materials and a robust design, ensuring durability and long-lasting performance. The use of this specific model on 1985 and 1986 Chevrolet applications subjected to Federal Emissions regulations further emphasizes its capability to meet and maintain fuel efficiency and regulatory requirements.

In summary, the Rochester Quadrajet carburetor model number 17085215 is a performance and emission-compliant fuel delivery system, designed for 1985 and 1986 Chevrolet applications. It features four-barrel design with a Quadjet secondary system, an electric choke and optional air metering devices for better cold starting, and high-quality construction materials for durability.
