The Needle Seat is a genuine spare part manufactured by Piaggio so you have peace of mind the Needle Seat part being sold by Motorcycle Spare Parts is both original and new.
The Needle Seat, carrying the manufacturer part number CM102203, is an essential OEM replacement automotive part compatible with several popular brands, including Aprilia, Derbi, Moto Guzzi, Vespa, Gilera, and Piaggio.
Functionally, the needle seat is an integral part of the motor's carburetor system. It works closely with the float needle to control the fuel level in the carburetor bowl, a factor that substantially impacts the engine's overall performance and efficiency.
In more detail, as the carburetor bowl fills with fuel, the float raises, which, in turn, pushes the float needle into the needle seat. This action effectively blocks fuel flow into the bowl, preventing flooding. As fuel is consumed by the engine and the level in the bowl drops, the float lowers, pulling the needle from the seat and allowing more fuel to flow into the bowl. In this way, the needle seat is instrumental in achieving a delicate balance that supports optimal engine operation.
Regarding its type, the CM102203 Needle Seat is a metallic, precision-engineered part designed to withstand continuous contact with the float needle and the chemical harshness of the fuel. Its design and materials are chosen for durability and resilience, aiming to provide reliable performance over long usage periods. Maintaining a properly functioning needle seat is critical for the effective operation of the carburetor and, by extension, the engine.
