Polini CP 19mm Carburetor Manual Choke Clamp Mount 201.1904

The genuine Polini CP 19mm carburetor with manual choke, part number 201.1904, has been fully designed and manufactured by Polini for sporty 2-stroke scooters, mopeds and geared motorcycles. Its compact aluminium construction, low weight and efficient airflow provide crisp throttle response and accurate fuel metering.

With its 19 mm venturi, this Polini CP carburetor is suitable for sporty and mildly tuned 2-stroke engine setups. The centrally positioned air inlet sits directly in front of the venturi, ensuring efficient airflow throughout the throttle range. This results in stable fuel atomisation, accurate mixture formation and predictable throttle response.

This version features a round throttle slide, a manual choke, and connections for fuel, vacuum and oil, making it suitable for a wide range of 2-stroke engine configurations.

The carburetor has a 24 mm clamp-on connection and can be used in combination with a suitable clamp-on intake manifold. The air filter connection has a diameter of 46 mm.
