Carburettor Polini CP 17.5mm, clamp flange, for Vespa 16.16 intake manifold

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.
