The 6R-7950B is a double-pumper, vacuum secondary carburetor, which means it provides a smooth and consistent fuel delivery under varying engine loads.

The combination of these materials ensures long-lasting performance even in the harshest environments.

The carburetor is equipped with a 1-1/16" throttle bore, which allows for easy airflow and a smooth throttle response. The venturi shape is optimized for a wide fuel bowl, providing ample fuel volume for reliable operation in a variety of conditions.

The 6R-7950B is also notable for its adjustability. The primary and secondary metering jets, as well as the secondary air gap, are easily adjustable using the included Allen wrenches, allowing for fine-tuning to achieve the optimal fuel/air mixture for your specific engine application.

Additionally, the carburetor includes a 10-blade accelerator pump, which ensures rapid fuel delivery during acceleration. The pump is vacuum-actuated to minimize power draw from the engine. The carburetor also features a factory-set 650 CFM air cleaner element for optimal air filtration.
