B) Replacing the carburettor
– Follow steps 1 - 2 -3 - 4 - 10 of the procedure
described in point "A".
C) Adjusting minimum speed
21 Check that the throttle cable is adjusted cor-
rectly [u 6.5.A].
22 Let the engine heat up for a few minutes, then
set the throttle control to "SLOW". Check the
rotation speed on the speed indicator (31).
NOTE
The engine's minimum speed must be between
2200 and 2400 rpm.
23 Turn the screw (32) until you achieve a stable
minimum speed within the above values.
D) Adjusting maximum speed
NOTE
This operation is carried out by adjusting the
governor system [u
E) Adjusting the carburation
NOTE
The carburation is set in the factory and does
not normally need changing. In special cases
such as, for example, if the lawnmower is used
at altitudes above 1200-1500 metres, it could
be advisable to modify the initial calibration. The
following must be borne in mind when adjust-
ing:
– carburation that is too lean leads to irregular
operation and difficulty in keeping the revolu-
tion speed constant;
– carburation that is too rich causes the engine
to flood.
31 Carburation adjustment is done using screw
(33):
– screwing in, to reduce the amount of fuel;
– screwing out, to increase it.
NOTE
To reset the optimal condition, fully tighten
screw (34) and then unscrew it by about 1.5 – 2
turns.
