Move the stator counterclockwise, advancing the timing
until the continuity reading breaks and reads zero.
Tighten the stop bracket to secure the stator.
Loosen the actuating cam locking screws just enough
to allow adjustment of the cam. Move the actuating
cam to open the throttle completely WITHOUT causing
any binding with the throttle post.
To coordinate the carburetor idle with ignition timing,
rotate the crankshaft clockwise, to .003'’ After-Top-
Dead-Center (ATDC).
Rotate the control lever toward the idle position until
continuity is obtained.
Move the throttle actuating cam until it just touches
the throttle post, without moving it.
Tighten the screw slightly, then check the run position
and idle position alternately to make sure the actuating
cam is adjusted for both positions. Now tighten the
screws.
Using a dial indicator, set the piston to the specified
Before-Top-Dead-Center (BTDC) dimension.
OUTBOARD TIMING. (SOLID STATE) . Follow these
step-by-step procedures outlined for timing outboard
engines with solid state magnetos.

Install timing tool 670238A on the crankshaft, be careful
not to distort the keyway area.
Without disturbing the BTDC piston position, move
the control lever counterclockwise until the run trigger
aligns with the timing tool (670238A) notch marked
#1. Hold this position.
NOTE: Some models do not have the “start” trigger.
