650 CFM Aluminum Screamin' Demon Carburetor-Factory Refurbished

This is an official Demon Factory Refurbished Carburetor. Factory Refurbished carbs are NOT old worn-out carbs that have been rebuilt. They are 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 Demons are the latest development in the evolving family of Demon performance carburetors. Screamin' Demons were designed with the weekend racer in mind. They are available in 650-850 cfm mechanical secondary models, as well as a 750 cfm vacuum secondary model. Screamin' Demons feature lightweight die-cast aluminum construction, large capacity fuel bowls complete with dual sight glasses, dual threaded inlets on each side, and internal baffling to prevent fuel slosh when you are on the track. Engineered and calibrated for better drivability and full throttle performance, Screamin' Demons include four corner idle, changeable idle and high-speed air bleeds with all the tunability that you would find from more expensive carburetors in the market.
