INTAKE AND EXHAUST VALVE TIMING PROCEDURE
TIMING ADJUSTMENT (Continued)
8. Verify setting.
a. Check valve timing by rotating flywheel 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.
b. Stop rotating the flywheel the instant the valve adjusting screw pad (12) becomes free.
c. Observe position of flywheel timing
mark "6R INT CLOSE .100 CLR" (A).
d. When timing mark (A) is aligned within
1/8 inch of engine timing mark (B), the
valve timing is correct.
e. If timing mark is not aligned within
1/8 inch, withdraw shouldered shaft and
repeat steps 3 through 8.
When correct timing cannot be obtained as described above, it may be
necessary to set timing mark (A) 1/8 to 1/4 inch out of alignment with
mark (B) before installing shouldered shaft (22).
