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 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 w/threaded shalf...
• Force Pull Start Engines required NO spacer and no shaft cutting.  The engines comes with an alum cast driver 
washer, you use this part as the spacer, not the alum. washer shown.  Also, use the special flywheel brass corn.  
This corn fits the thread shaft diameter so you can tighten the flywheel against the drive hub.
