Part # FR-80681 Be the first to write a review
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, but it also 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 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 the previous installation. Factory Refurbished Carburetors have limited availability. Performance is one thing, but with low-riders looks are everything. The Lo-Rider Avenger features chrome fuel bowls, a polished main body, and accented with gold hardware for a show winning appearance right out of the box. The 670 CFM Lo-Rider Avenger's specialized fuel metering system and one-piece vent tube prevent stalling and flooding during extreme leaning and bouncing maneuvers. The Lo-Rider Avenger features an electric choke for quick and smooth engine warming. The vacuum secondary design allows the Lo-Rider Avenger to be used on a broad range of engine and vehicle applications. (Viton® is a registered trademark of DuPont Performance Elastomers) This model of carburetor has the square bore flange bolt pattern. It can replace Holley, Edelbrock, Carter AFB, and Autolite style carburetors with a 5 3/16" x 5 5/8" bolt pattern. If you have a spread bore style intake manifold, you will need an adapter to install this carburetor. Similar to the Mr. Gasket #1932.
