Sierra Remanufactured Carburetors
Sierra Carburetors are precision remanufactured to meet or exceed OEM specifications. Sierra Carburetors have been re-calibrated and re-engineered to maximize fuel efficiency and performance. All carburetors are flow tested throughout the entire throttle range. Fuel mixture and idle settings are pre-set to ensure that only minor idle and choke adjustments are necessary during installation. All bases are resurfaced, and throttle shaft bushings are replaced. Base gasket is included.
