Part # FR-4224 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. The Holley 660 CFM Center Squirter carburetor is just as much at home on a competition vehicle as it is on a show vehicle parading around the fairgrounds. Designed for 2 x 4 in-line tunnel ram applications, the 0-4224 carburetor features a competition fuel curve to provide safe and reliable horsepower, no choke for improved airflow, 1 to 1 mechanical secondaries for tire turning power, and a unique center accelerator pump discharge nozzle for the perfect amount of initial fuel.

Features:

  • Gold Dichromate finish for corrosion resistance and classic Holley looks
  • Calibrated for use with a 2x4 intake set-up
  • No choke for unobstructed airflow
  • 1:1 mechanical linkage for awesome tire turning performance
  • 50cc center discharge pump for the right amount of fuel in all four bores under initial acceleration
  • Single feed fuel inlet for easy installation
  • 100% wet-flow tested by Holley technicians to assure it arrives ready to run!
