The 233-717 Tillotson Fuel Inlet Needle, Seat, and Gasket Kit is often used on gas carburetors, and the fuel inlet seat is designed for HW Tillotson Carburetors. 

Check your carburetor listing, or better check the orifice before installing a new seat.

The Fuel Inlet Needle is known as a captured needle. This is because the fulcrum arm lever "captures" the dowel on top of the needle with the fork on the lever. The captured needle is used to keep the fulcrum in contact with the needle at all times during operation. Many have used them when tracks are rough or when the carburetor's fuel inlet is facing downward.

When replacing your seat, it's important to measure the length and the fuel orifice to have the correct seat for your carburetor, especially ones that have been blueprinted, built, or modified.
