22. Check valve timing by rotating flywheel (47) clockwise, as viewed from the rear, approximately 1/8 turn to remove
gear backlash, then turn counterclockwise until the intake valve is just closed. Stop rotating the flywheel (47) the
instant the valve adjusting screw pad (55) becomes free.
23. Observe position of flywheel timing mark (51). When timing mark on flywheel (51) is aligned within 1/8 inch of
engine timing mark (49), the valve timing is correct. When timing mark is not aligned within 1/8 inch, withdraw
shouldered shaft and repeat Installation steps 5 through 22.
NOTE
When correct timing cannot be obtained as described
above, it may be necessary to set timing mark (51), 1/8 to
1/4 inch out of alignment with mark (49), before installing
shouldered shaft.
