This is an official Holley Performance 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 carburetor! Factory refurbished carbs have undergone a thorough inspection. Any damaged parts that would affect 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. Any defective items will be repaired or replaced at Holley's discretion.
