The CP Evolution series is a top-of-the-range version of the conventional Polini 'CP' carburettor, and uses a clever trick to take advantage of the positive effects of a large carburettor to give more engine power and more torque.
After the slide the carburetor passage opens once again, up to an even larger 26mm diameter (CP24 = 26mm). Thus this small Polini CP Evolution 24mm carburettor produces more power than a Dell'Orto PHBL25 carburettor! Due to the small dimensions and the integrated intake funnel, the CP carburettor is ideal for all scooter engines where a small physical size is an advantage.
The carburettor has a round slide and connections for vacuum/oil (rubber caps included). The main nozzle is identical in construction to the Keihin PWK, although all other fine-tuning parts are Polini's own. The carburettor has a cable operated cable choke (choke cable not included), or a flip up choke can be chosen.
Possibility to purchase this carb with RLC's (base / starting point) carburettor settings for the Casa Performance 'CP One35' 135cc cylinder kit for Lambretta J + Lui models.
