Carburettor DELLORTO PHBH 28 AS rigid choke lever without separate greasing or depression

Here is the PHBH AS 28 carburetor from DELLORTO. PHBH models are widely used in competition, particularly on cylinders with round exhaust or boosters, they certainly offer less recovery, less torque or less acceleration than a flat valve carburetor for example, but they offer excellent power and significantly improved high revs. They are also used on many original machines!

They are extremely stable, easy to adjust and of excellent quality. We only sell genuine DELLORTO certified carburetors! Here it is the reference 3318 machined from quality aluminum materials with a smooth and clean finish.


This carburetor is a model with a lever choke, it does not have separate greasing, so you will either have to mix it up or have a mixture socket on the intake pipe. On the PHBH, the main jet is very easy to change, in fact you just need to unscrew the tank cap, the jet is inside.

This high-performance and solid carburetor will give you all the performance you want on your large engine configuration on mopeds, scooters or even mécaboite! In addition, the PHBH bodies have a threaded air filter fixing diameter of 42mm, possibility of installing the tulip delivered with the carburetor for a larger air inlet (better ventilated) in diameter 60mm.
