Reassembly of machine covers
Check that the spark plug (1) electrode gap is
0.6-0.7 mm. Fit the spark plug, and tighten it to the
stipulated torque load.
Locate the air filter (3) in the filter housing and fit the
filter cover (4).
Fit the fan cover (6) with the two screws (7) and the
starter cover (8) with the three screws (9).
Fit the rear cover (10) with the four nuts (11).
Note: With the front cover removed, easy access is
provided to the throttle cable adjuster screw.
Throttle cable adjustment
Slacken the lock nut (1). Use the adjuster screw (2)
to set the tension of the cable so that the idling
speed is not affected by any movement caused by
the anti-vibration springs.
Check the tension by pressing the springs down to
their stop position. The throttle valve must not be af-
fected, i.e. the idling speed must not increase.
Note: The throttle cable must not be so loose that it
risks jumping from the carburettor cable wheel (3).
Fix the setting by tightening the lock nut (1).
Front cover
Fit the front cover (1) and tighten the four nuts (2).
Press in the spark plug spanner (3) and screw the
service cover (4) in place with the rubber expander
(5) and the screw (6).
