carburetor Dellorto PHBN 17.5mm LS for Minarelli, CPI

Dellorto 17.5 mm carburettor. For scooters with Minarelli or CPI engines. Recommended even for untuned engines, as the carburettor is easier to tune than the original. Flat spots and idling problems become a thing of the past. An absolute must for 70cc cylinder kits! Only the correct size carburettor can ensure the required cylinder cooling, which avoids expensive damaged to the bore. The carburettor is prepped for the original manual choke (not supplied). For scooters with an E-choke, please see item no. 11057. The original air box can also be retained. Jetting: Main Jet 90+, Pilot Jet 34, throttle needle A12. This carburettor uses Dellorto main jets with an M6 thread. Type: PHBN 17.5 LS
