Dellorto PHBN 12BS with Cable choke as a replacement part for a defective carburettor. The PHBN 12BS 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 defective OEM carburettor with a new replacement part.
