11. Check valve timing by slowly rotating flywheel (8) counterclockwise, as viewed from flywheel end, until No. 6R
intake valve is just closed. Closing point is determined by trying to rotate the valve adjusting screw pad (17) on
the intake valve adjusting screw (16) while the flywheel (8) is being rotated. The valve is closed the instant the
valve adjusting screw pad (17) is free to move.
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, the
timing must be adjusted. Go to adjustment.
