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. Serious drag racing demand a serious drag racing carburetor, and the QFX-Series stands as the flagship model in QFT's lineup. Raised air horns improve entry angle into the venturi while ensuring undisrupted flow over the air bleeds. Annular boosters with CNC-machined billet aluminum inserts provide increased air flow, a stronger signal, and less turbulence. QFX carbs offer unparalleled fuel atomization with annular boosters specific for either gas, methanol, or E85 fuels. Five-emulsion billet metering blocks and four-corner idle circuits offer flexible tunability that today's high-horsepower engines demand. To cover a broad range of applications, methanol- and E85-compatible models, as well as two- and three-circuit fuel systems, are available. Ready to run out of the box, the QFX-Series carburetor will help you get to the winner's circle. •QFX aluminum main body w/raised venturi •Billet aluminum metering blocks with screw in restrictions •Aluminum fuel bowls with dual sight windows and fuel inlets •Nitrophyl® Floats (notched rear) and jet extensions •Viton .130" Needles and Seats •Billet Aluminum annular booster inserts •QuickLink™ adjustable secondary opening adjustment •Hand assembled and engine tested
