Polini CP 21mm Carburetor Cable Choke Spigot Mount 201.2101

The genuine Polini CP 21mm carburetor with cable choke, part number 201.2101, has been fully designed and manufactured by Polini for sporty and tuned 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 21 mm venturi, this Polini CP carburetor is suitable for powerful 2-stroke engines, including sporty 50cc and 70cc setups. The centrally positioned air inlet sits directly in front of the venturi, helping to maintain stable airflow at every throttle slide position. This results in consistent fuel atomisation and predictable engine response.

This version features a round throttle slide and a cable-operated choke, allowing remote choke operation 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.
