Carburetor DELL’ORTO PHBL 22 AD AD air filter connection: 37.5mm, Dell’Orto PHB connector Series carburetors are the first choice for the mid-range tuning area. They belong to the carburetor drum category (rounded throttle valve) and are available for smallframes (PHBL) and largeframes (PHBH) with a 24-30mm socket. Dell’Orto PHB carburettors are also the right choice for all those who want to get the best possible performance from their scooter at the lowest possible expense. Their design is more complex than on the SI or SHB, but Dell’Orto PHB carburettors also have more room for individual settings. These can be done with a reasonable combination of slides (available with different inserts), the needle, calibrator and jets from the Orto’s wide range of products. The carburettors we supply have a basic setup that allows for trouble-free installation. The second corresponding motor fine tuning must be completed within the individual and specific to the motor in question! The denomination ‘S’ (ital. Left = left) on carburetor means: Mix adjusting screw to the left of the induction direction, ‘D’ (ital. Right = right), it means: Mix adjusting screw to the right of the induction direction. This is important for installing the carburetor. The carburettors come with a flip-up choke as standard, but can easily be converted to a hollow choke (e.g. no part 40320000) with the matching kit. Conclusion: The best value for money. Perfect midrange tune for those with more limited portfolios. SIP-TIP: Mandatory in all circumstances: suitable intake manifolds (see connection width), sport air filter and air bellows. The best idea is to experimant with the jet kit (for example part no 40270200) when filling out the setting jobs!
