3. Insert the four M4 x 20 machine screws through the holes
in the mount and into the holes drilled in the previous
step.
4. Place the four M4 washers on the screws, then thread the
M4 locknuts onto the screws. Use a 7mm nut driver and
#2 Phillips screwdriver to tighten the screws.
5. Position the engine between the engine mounting rails.
Adjust the engine so the distance between the face of
the fi rewall and face of the drive washer is 53/8 inches
(137mm). Use clamps to hold the engine securely to the
engine mounting rails.
6. Mark the position of the rear engine mounting bolts using
an 11/64-inch (4.5mm) drill bit. Remove the engine from
the rails, then drill the holes for the engine mounting
bolts.
We recommend removing the mounts from the
fuselage and using a drill press to drill the holes, so
they are aligned square to the mounting rails.
7. Place the engine back between the rails and insert either
6-32 x 11/4-inch machine screws (not included) or M4
x 30 machine screws (not included) through the rear
mounting holes and the mounting rails to position the
engine. Use a felt-tipped pen to mark the location for the
front mounting holes. Drill the holes are outline in the
previous step.

8. Secure the engine to the mounting rails. Use four M4 x 30
machine screws, eight M4 washers and four M4 locknuts.
9. Use a drill and 5/32-inch (4mm) drill bit to drill the holes
for the throttle pushrod.
10. Locate the hole outside the tank tray, and directly above
the lower engine mounting rail.
11. Prepare the stopper assembly by placing a small amount
of solder on the end of the tubes shown. This will help
keep the fuel lines secure when installed. Use care not
to overheat the tubing, which could melt the stopper
material.
12. Secure the tubing to the clunk and tube from the stopper
using thin wire. This will keep the tubing from sliding
loose inside the tank.
