Carburettor DELL`ORTO FHBA
28.20 for Vespa PK 125 S
The Vespa PK Automatica models are also equipped with carburettors manufactured by DELL'ORTO as standard equipment. We only have the FHBA 28.20 carburettors available for the PK 125. The carburettors that were originally included with the PK 50 (FHBB 16.12) and the PK 80 Automatica (FHBA 24.18) are regrettably no longer in production by DELL'ORTO. Alternatively the FHBA 28.20 carburettor, also produced by DELL'ORTO, is fully compatible for use with the PK 80 Automatica. In contrast to the SHB range of carbs they do not possess a throttle side, but are equipped with a butterfly valve with the tickover adjustment screw located near the bottom. The tickover fuel/air mixture adjustment is located towards the top of the carburettor. It shares its main jets (6mm) with those also used on the PHB range of carburettors, the secondary jets can also be found on the SI range, all produced by DELL'ORTO.
Conclusion : These carburettors represent a completely viable alternative to the original carburettor type.
SIP-TIP : The gaskets suitable to fully seal these carburettors are available as part of the complete motor gasket set (#92014000).
