Notes:
Non-Pull Start Engines...
• Alum. Washer behind the flywheel is not needed when using Force engines or similar types. O.S. Engines will
require washer spacer.
• To check!..place the brass corn #10330 (big hole) against the engine bearing, then flywheel. You should be
covering one or two thread of the engine shaft. If this is the case, you do not need an additional washer behind the
flywheel.
You must cut the engine shaft if too long. Count 6 threads in front of the flywheel and mark. This is all you need to
tighten the clutch nut and mount the flywheel.
Force Pull Start Engine...
• Force Pull Start Engines required NO additional spacer and no shaft cutting. The Force engines comes with an
alum. cast driver washer, you use this part as the spacer, not the alum. washer shown for O.S. installs
But, you must find the #10329 brass corn (sml hole) for Flywheel. This special corn fits the smaller thread
diameter of the engine shaft. It will center the flywheel when tightening the clutch nut.
*Tighten the strap
and cut off the excess.
