Review AUTOLITE Section Only Carburetor

The Autolite C9OF-R Center Carburetor is a classic fuel delivery system designed for vintage automobiles and hot rods. This carburetor is a center-mounted, single-barrel design, offering efficient combustion and smooth engine performance.

The C9OF-R is a refined version of the original Autolite center carburetor, featuring several improvements that enhance its durability and ease of tuning. It comes with an electric choke system, which ensures easy starting, even in cold weather conditions. The choke plate is operated by a vacuum-operated switch or an external electric switch, providing the driver with the flexibility to choose their preferred starting method.

The carburetor body is made from high-quality aluminum, ensuring lightweight construction while providing excellent heat dissipation. The barrels are constructed from chrome-molybdenum steel, a material known for its high strength and resistance to corrosion. The throat and main jets are precision-machined to deliver accurate fuel mixture for optimal engine performance.

The C9OF-R features a primary and secondary fuel metering system, which helps maintain a consistent fuel-air mixture throughout the engine's RPM range. The secondary metering system, also known as the enrichment circuit, provides additional fuel to the engine during acceleration, ensuring smooth power delivery and improved fuel economy.

The carburetor comes with adjustable idle mixture screws, allowing the user to fine-tune the engine's idle speed and quality. Additionally, the carburetor's float bowl drain plug is easily accessible, making it simple to drain excess fuel in case of flooding or during maintenance.

The Autolite C9OF-R Center Carburetor is designed with a 1-3/4 inch primary venturi and a 2-inch secondary venturi. It is suitable for engines with a displacement range of 250 to 400 cubic inches. The carburetor comes with a gasket kit, mounting hardware, and instructions for a hassle-free installation process.

In summary, the Autolite C9OF-R Center Carburetor is a high-performance, durable fuel delivery system designed for classic cars and hot rods. Its features, including the electric choke system, adjustable idle mixture screws, and secondary fuel metering system, make it an excellent choice for enthusiasts seeking optimal engine performance and ease of tuning.
