Repair instructions
Function
The carburettor operates differently in the following
modes:
•
•
•
•
Cold start mode
Idling mode
Part throttle mode
Full throttle mode
In the cold start mode (see figure) the choke valve
(H) is fully closed. This increases the vacuum in
the carburettor so that fuel is sucked more easily
from all the diffuser jets (D, E and F). The throttle
valve (I) is partly open. Extra air inlet (J) is closed
(see figure 25).
Fig 25
In the idling mode (see figure) the throttle valve (I
and J) is closed and the choke valve (H) is open.
Air is sucked in through an aperture in the throttle
valve and a small amount of fuel is supplied th-
rough the diffuser jet (D) (see figure 26).
Fig 26
In the part throttle mode (see figure below) the th-
rottle valve (I) is partially open and the choke valve
(H) is open. Fuel is supplied through the diffuser
jets (D and E). The throttle valve (J) starts to open
(see figure 27).
Fig 27
In full throttle mode (se figure below) all valves
are open and fuel is supplied through all diffuser
jets (D, E, F and G). Extra air inlet (J) is also fully
opened (see figure 28).
