The CP is the first caburettor that has been completely developed by Polini. Special attention has been paid to size and weight: the carb is very compact and about 40% lighter as compared to traditional carbs. The compact design makes for a very short intake tract. The venturi has a unique concentric design (in contrast to the conventional oval ones) and therefore a geometry that optimises air flow. A revised emulsion tube and a bigger needle improve the atomising of the fuel mixture. This is expected to offer an easier set-up and high performance coupled with low consumption. All CP carbs are equipped with oil feed and vacuum connection. There are versions with pull-type choke and with cable attachment.
