"The Polini CP carburetor is lighter than other carburetors available on the market and under certain conditions it may cause fuel emulsion problems. Air bubbles are sucked into the main jet casing very serious problems to the engine that becomes poor despite having a big or correct jet; the engine begins to detonate up to its break. Fit the transparent bowl (cod.343.0029) that will allow you to detect the problem and, if necessary, soften the rubber manifold until the problem disappears. If the problem persists, increase the mass of the carburetor mounting the filter coupling iron flanges (THIS PRODUCT, cod.343.0028) produced by POLINI. Once the problem has been solved fit the standard bowl again.
