If your carburettor is beyond repair, then it will require replacement with a new item. We have the original carburettors, fitted by PIAGGIO, for every model of Vespa available from stock. The KEIHIN CVK carburettors are used by PIAGGIO for all of their modern four-stroke Vespa motors. On the other hand, they mostly use DELLORTO PHVA carburettors for their modern two-stroke models. If your two-stroke has a different make of carburettor fitted originally, the DELLORTO item is fully compatible for use. All carburettors are delivered fully assembled and include an electrically operated choke mechanism.
SIP-TIP : Always use the correct size of hose clamp to secure the carburettor between the air bellow and manifold.
