Dellorto PHVA 12QD as a replacement part for a defective carburettor. The PHVA 12QD shares the carb set up with the other listed vehicles. Some variation in the jets may occur as some scooters were kitted with a catalytic convertor. For this reason, at least the main jet should be matched with the main jet in the factory carburettor. Fits the original air box and intake manifold. Perfect replacement for those who need to replace the faulty OEM carburettor with a new replacement part.
