Adjust the stop bracket to prevent the control lever
from moving any further counterclockwise. Then tighten
the stop bracket screw.
Loosen the actuating cam lock screw enough to allow
adjustment of the cam. Position the cam so that it
opens the throttle completely, making sure that the
cam doesn’t cause binding on the post.
When the correct position is attained, tighten the lock
screw on the “high” end to hold the cam in place.
Move the control lever to align the “RUN” trigger of
the ignition unit with the number 2 position of the timing
tool. Hold this position.
Adjust the actuating cam to touch the post without
moving it. Tighten the lock screw to hold the cam in
place.
Recheck to insure that the high speed point hasn’t
changed or that binding will not occur. Readjust from
the high speed point to the pickup point as necessary.
When assured that the cam position is correct at the
FULL RUN and IDLE positions, torque the lock screw
to 10-15 in. lbs.
