This seat has the largest orifice for flowing fuel in the Tillotson catalog. It's often used in gas carburetors, mainly rotary and reed valve 2-cycle race engines, big displacement piston port 2-cycle, and large 4-cycle engines. But for many small-displacement engines with smaller carburetors, the seat is used to run methanol 4-cycle engines.
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 essential to measure the length and the fuel orifice to have a correct seat for your carburetor, especially ones that have been blueprinted, built, or modified.
