Quick fuel carburetors are amongst the highest quality carburetors on the market. They are hand assembled and engine tested here in the USA. Carburetor has been tumble polished for a beautiful long lasting shine. The SQ-750 is a double pumper carburetor and features mechanical secondary and has no choke horn for better air flow. Q-Series carburetors are purpose-built for the dragstrip. To combat the g's experienced during hard launches, Q-Series carbs are equipped with notched floats and secondary jet extensions. The high-flow aluminum main body isn't just lightweight, but it also features recessed air bleed cavities for improved air flow. Other standard features include screw in air bleeds, high speed bleeds, idle feed restrictions, power valve channel restrictions, dual metering blocks, 4-corner idle, built-in sight glasses, tunable secondary opening rate and down leg boosters.
