HOW TO SET THE CAMSHAFT TIMING

When replacing the camshaft, set the timing as
follows.

If propeller is not secured, crankshaft may
move backward and correct timing cannot
be set.

drive hub may match crankcase center line.

until it stops. Locate ' •' mark on the side of
camshaft gear in line with the push rod.
4. Rotate crankshaft right and left a little and
make sure that the ' •' mark on the gear is in
line with the push rod when the ' T ' mark on
the drive hub matches the crankcase center
line.
