The 233-705 Tillotson Fuel Inlet Needle, Seat, and Gasket Kit is often used on gas carburetors, and the fuel inlet seat is sometimes referred to as a gas seat or, in this case, a long gas seat.
These are due to the fuel seat orifice being smaller than seats used in carburetors running methanol. Be aware that this does not mean because you have a gas carburetor; it needs a "gas" seat. Check your carburetor listing, or better, check the orifice before installing a new seat.
The Fuel Inlet Needle is known as an uncaptured needle. The fulcrum arm lever does not "capture" the needle instead;, the lever tap sits on top of the needle. This type of needle is commonly used on a 4-cycle kart engine where the carburetor fuel inlet is usually facing upward.
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.
