CARBURETTOR
Operation
The carburettor operates differently in the
following modes:
•
•
•
•
Cold start
Idling
Part throttle
Full throttle
In the cold start mode the choke valve (D)
is fully closed. This increases the vacuum
in the carburettor and fuel is easier to suck
from all the diffuser jets (E, F and G). The
throttle valve (H) is partly open.

In the idling mode (H) the throttle valve is
closed. Air is sucked in through an
aperture in the throttle valve and a small
amount of fuel is supplied through the
diffuser jet (G).

In the part throttle mode the throttle valve
(H) is partially open. Fuel is supplied
through the diffuser jets (F and G).
