This carburetor is available in a variety of configurations for street, strip, and track performances. Dual accelerator pumps aid the performance of the manual transmission, strip gearing, and engines built for top-end horsepower. It is equipped with a fuel bowl with a center or side pivot float and an externally adjustable needle and seat assembly which allows the float level to be easily adjusted. The manual choke system is designed to supply a rich fuel mixture to the engine for cold starts and drive-away conditions.
