Quick Fuel Black Diamond Q-Series 2-Barrel Carburetors

High performance Quick Fuel Black Diamond Q-Series 2-barrel carburetors have been engineered for circle track applications. They feature a high-flow aluminum main body with centered venturi for improved fuel distribution and efficiency. An anti-siphon check valve in the main body helps to reduce pump pullover, and the straight leg boosters enable higher airflow. Q-Series carbs have changeable emulsion bleeds and power valve channel restrictions for better tuning capabilities, as well as adjustable idle mixture screws, power valve blowout protection, and built-in dual sight glass windows for easy float adjustment. The unique PTFE coating provides a highly durable black satin finish; it's impact- and scratch-resistant, and impervious to underhood chemicals. This PTFE coating also offers a 6 percent reduction in fuel temperature, further enhancing your vehicle's performance.
