Overview

This is an official QuickFuel Factory Refurbished Carburetor listing. Factory Refurbished carbs are NOT old worn-out carbs that have been rebuilt. They are brand new carbs that were returned under warranty. When these carbs are returned, we check them out and most of the time there is nothing wrong with them. Generally, they were simply adjusted out of working range by the installer. Since these carbs may show signs of a previous installation, our policy is not to sell them as new. Rather than scrapping them, we are making them directly available to the public. Not only does this help us control the costs of our new carbs, it allows you to get a great deal on a like-new carburetor! Factory Refurbished carbs have undergone a thorough inspection. Any damaged parts that would effect performance have been replaced and the carbs are solvent cleaned before being wet-flow-tested on Holley's state-of-the-art flow benches allowing them to be recalibrated to new carb specs. Factory Refurbished carbs may have scratches, blemishes, and other visual flaws from previous installation. Factory Refurbished Carburetors have limited availability. Ideally suited for bracket racers and weekend warriors alike, 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. Die-cast venturi are machined to exacting tolerances for outstanding throttle response. Billet metering blocks ensure a uniform fuel curve, while throttle-bodies enhance durability. For those days when track conditions vary from one pass to the next, QFT's QuickLink system makes adjusting the secondaries easy on models equipped with mechanical secondaries. The Q-Series is our most comprehensive line of carburetors, with applications available for use with gasoline, methanol, and E85 fuels, forced induction, drag race, circle track, and comes in both vacuum and mechanical secondary models.
