This is a brand new Tillotson carb HL324A that has been modified to bolt right on the snorunner and works great. Carb has a 1" bore for air flow instead of the 7/8" Bore on original carb. Which will give it more power. It comes with the Black plastic throttle slide box and Plastic air cleaner base which were modified to work on this carb. This is a different model carb then original so the chock lever is different. Brand new carb and Plastic parts. It only comes with what you see. Gasket included. Ready to bolt on!.
