Maintenance Manual
On its way from the float chamber to the venturi, the fuel passes through the main
jet (7), the mixing tube and the needle jet and in the diffuser tube (8) is pre-mixed
with air which is brought in from the air filter via the air duct (9) and the atomizer
in an annular flow around the needle jet. This air flow assists the atomizing
process and favors fuel distribution in the manifold.
The jet needle (10), which is responsible for part load, is kept in the defined
position by the retaining clip (11).
