Note:
This needle and seat assembly is a Non-Windowed assembly.
The non-windowed N&S can help reduce the amount of fuel leaving the fuel bowl when the engine is shut off. Some vehicles draw fuel back out the carburetor and back to the gas tank. This non-windowed assembly will block the fuel from back flowing out of the fuel bowl and leave approximately .400" additional fuel in the fuel bowl. Needle and Seat Assembly - Non-Windowed, .124"
