The Rochester 7020980 2-Barrel Carburetor is a classic automotive component designed specifically for Oldsmobile F85 models with a 215 cubic inch V-8 engine produced between the years 1962 and 1963. This carburetor is an essential part of the vehicle's fuel delivery system, ensuring a proper air-fuel mixture for efficient combustion in the engine.

It comes with new gaskets, seals, and hardware to make the rebuilding process easier. The body is made of durable cast aluminum, ensuring long-lasting performance and resistance to corrosion.

The Rochester 7020980 2-Barrel Carburetor comes with a factory-set base circle size, which can be adjusted to fine-tune your engine's performance. It also features adjustable idle mixture screws and secondary throttle plates, providing you with the ability to make precise adjustments to ensure smooth idle and proper engine operation.

This carburetor comes with a 1-year warranty against manufacturing defects, ensuring that you're protected against any potential issues that may arise during the installation and break-in period. With proper installation and maintenance, this carburetor is designed to provide you with reliable performance and long-lasting service.

In summary, the Rochester 7020980 2-Barrel Carburetor is a high-quality, rebuildable component that is specifically designed for Oldsmobile F85 models with a 215 cubic inch V-8 engine produced between 1962 and 1963.
