Complete carburettor repair kit from 2EXTREME, suitable for 17.5 mm Dellorto PHVA carburettor. In the case of a leaking or non-clean carburettor, it does not always have to be replaced directly. Often only one seal is defective. With this repair kit, the carburettors can be repaired. The main and secondary nozzle is different depending on the scooter, so the nozzles included in the set may differ from the original nozzle. We recommend using the nozzle that is installed. The included secondary nozzle is a 43 and the main nozzle is a 98.
