11. Check valve timing by rotating flywheel (8) clockwise, as viewed from the flywheel end, approximately 1/8 turn to
remove gear backlash, then turn counterclockwise until the intake valve is just closed. Stop rotating the flywheel
(8) the instant the valve adjusting screw pad (17) becomes free.
12. Observe position of flywheel timing mark “6R INT CLOSE .100 CLR” (19). When timing mark (19) is aligned with-
in 1/8 inch of engine timing mark (10), the valve timing is correct. If timing mark is not aligned within 1/8 inch,
withdraw shouldered shaft and repeat steps 8 through 12.
NOTE
When correct timing cannot be obtained as described
above, it may be necessary to set timing mark (19) 1/8 to
1/4 inch out of alignment with mark (10) before installing
shouldered shaft (25).
