This CNC bored .675 carb is designed for the Stock Appearing or Outlaw class and offers a special built ultra thin throttle shaft and knife edge butterfly that greatly increases air flow. Reworked air circuits and a unique E-Tube help regulate the fuel signal to give you that "little extra" power and RPM you have been looking for. Available in Gasoline and Methanol versions. Both will come jetted and ready to race and require no extra work to the insulator or air filter adapter. Does not come with a choke.
