copy of Carburettor DELLORTO PHBN 17.5 LS flexible, with separate greasing, choke cable, depression ...

Here is the Ø17,5mm PHBN LS DELLORTO carburetor. This model has all the connections and sockets possible and very often mounted in place of the original carburetor on Minarelli / Yamaha 50cc 2-stroke scooters such as the MBK Nitro, Booster Spirit ... and many other machines.



It therefore has a separate greasing socket (you do not have to use it!), A vacuum, socket for antifreeze and a cable choke. If you do not use the sockets, remember to put a plug to avoid any malfunction. This carburetor is Ø24mm mounting. Its fixing diameter for air filter is 38mm unthreaded.



This low-cost carburetor is of very high quality and has a multitude of adjustments: richness screw, idle jet, needle valve… It consumes relatively little when it is perfectly adjusted! It offers much more performance than SHA carburettors and is below the PHBG in our opinion in terms of performance and possibility of evolution ...



Unlike rigid type carburetors, these types of flexible models absorb much better vibrations that are harmful to carburetion. Remember to check that your intake pipe accepts this carburetor, if not, remember to equip yourself with an intake pipe, sleeve ... adapted to install this carburetor as it should be, in the rules!
