Polini CP 19mm Carburetor Manual Choke Spigot Mount 201.1900

The genuine Polini CP 19mm carburetor with manual choke (part number 201.1900) has been fully designed and manufactured by Polini for sporty and tuned 2-stroke scooters, mopeds and motorcycles. Thanks to its compact aluminium body, lightweight construction and excellent tuning characteristics, the Polini CP series has become one of the most popular carburetors for road and racing applications.

With its 19 mm venturi, this carburetor is ideal for sporty 50cc and 70cc engine setups. In our workshop, we almost exclusively fit Polini CP carburetors on engines up to approximately 70cc because they are easy to tune and consistently deliver excellent performance.

This version features a round slide, a manual choke, a fuel inlet and two additional ports that are factory capped. This allows the carburetor to be used with or without a vacuum connection and oil feed connection, depending on the engine setup.

The carburetor features a 25 mm spigot connection and a 46 mm air filter connection.
