Tillotson Needle Seat Assembly Carburetor

Tillotson needle and seat assemblies are replacement carburetor fuel inlet components. They control how much fuel enters the carburetor's metering chamber. The needle valve seals against the seat to shut off fuel when the chamber is full. It opens as the metering diaphragm or float calls for more fuel. A properly sealing needle and seat helps prevent flooding, hard starting and rough running. It also helps keep fuel delivery and idle and mixture tuning consistent.
