OUTBOARD TIMING
OUTBOARD TIMING. (STANDARD IGNITION) . Follow
the step-by-step procedure outlined for timing outboard
engines with Standard ignition magnetos (non-solid
state).
Apply a small amount of E.P. Lithium grease to the
contact area of the friction screw. Do not turn the
screw into the radius of the stator collar.
Install the stator with operating handle pointed in the
direction of the carburetor. Be sure the throttle post
is NOT INSIDE the arc of the throttle actuating cam.
Hold the throttle open when installing the stator.
Move the control lever to full retard, then move toward
full advance while tightening the friction screw until
the lever will not vibrate out of position when the engine
is running and yet can be easily rotated when speed
is adjusted.
Adjust ignition points to proper specification.
Remove leads from point terminal, then reinstall and
tighten the nut and washer. Attach a continuity device
to the point terminal post and to a good ground on
the engine as shown.

Clean points by sliding lint free paper back and forth
between the contacts. Manually open points when
removing paper to eliminate paper fiber from remaining
between contacts.
Using a dial indicator, set the piston to the proper
Before-Top-Dead-Center (BTDC) to the specified
dimension.
