1. Place a Countersunk Washer (172) over each of the 5-40 x 1/2"
Flat-Head Screws.
2. Position the engine in the Chassis (19) and line up the holes in
the Engine Mounts (164) with the slots in the Chassis.
IMPORTANT NOTE: Use a Thread-Lock compound on the
threads of the screws in the Engine Mounts to keep them from com-
ing loose.
3. Thread the 5-40 x 1/2" Flat-Head Screw (173), with the Washers
in place, all the way into each of the four holes in the Engine Mounts.
Be sure all the Countersunk Washers fit down inside the slots in the
Chassis. Do not fully tighten the Screws yet.

1. Adjust the Gear mesh between the Clutch Bell (159) and the
Spur Gear (91) by sliding the Engine Mounts (164) in the slots of the
Chassis (19). In order to function properly, the Gears should be as
close as possible, but still have a small amount of backlash (space
between the Gear teeth). You should be able to rock one Gear back
and forth slightly while holding the other one steady. Be sure to
check the Gear mesh all the way around the Spur Gear.
2. Once the engine alignment and Gear mesh are correct, tighten
all of the Screws (173). Re-check the Gear mesh after all the Screws are
tight to ensure the Engine Mounts did not move.
Place a piece of paper between the Clutch Bell Gear
and Spur Gear, Slide the engine forward until the paper is pinched
between the Gears and Tighten the Engine Mounting Screws. This
will give a small amount of space between the Gears for proper mesh.
