Polini CP 19mm Carburetor Cable Choke Spigot Mount 201.1901

The genuine Polini CP 19mm carburetor with cable choke, part number 201.1901, has been fully designed and manufactured by Polini for sporty 2-stroke scooters, mopeds and geared motorcycles. Its short body, low weight and precise tuning options make it highly suitable for sporty road setups and mild engine tuning.

With its 19 mm venturi, this Polini CP carburetor provides a good balance between torque, airflow and crisp throttle response. The air inlet is positioned centrally in front of the venturi, helping to maintain efficient airflow at every throttle slide position. This supports stable fuel atomisation and predictable engine response.

This version features a round throttle slide and a cable-operated choke, allowing the choke to be operated remotely with a suitable choke cable. The carburetor also has connections for fuel, vacuum and oil.

The carburetor has a 25 mm spigot connection and can be installed with a suitable spigot-type intake manifold. The air filter connection has a diameter of 46 mm.

Polini checks the CP carburetors at several points during production, including float needle sealing and the float level. This provides a reliable starting point, but the carburetor should always be tuned to match the cylinder, exhaust, ignition and air filter configuration.
