NOTE:
Secure the dial gauge after retracting it by ap-
proximately 3mm (0.118 in).
6. Slowly turn the flywheel clockwise observ-

8. Slowly turn the flywheel clockwise until the
#1 cylinder piston comes to the specified
position.
60H30235
NOTE:
To move the piston to the specified position,
flywheel should be turned almost one full revo-
lution, and the pointer mark on the timing plate
should come close to BTDC 18° marking on
the flywheel.
9. Adjust the position of timing plate
5
so that
the pointer mark
A
comes to the full ad-
vance angle on the flywheel scale.
