Step 4
Center the engine mount in relation to the oval holes
in the firewall. Tighten the bolts holding the mount
to the firewall. (Remember to make sure the barbs on
the blind nuts go into the backside of the firewall.)
Note: Install the screws and blind nuts
one at a time so the mount doesn't
change positions on the firewall.
Step 5
Determine the proper location for the throttle pushrod.
Mark the location with a felt-tipped pen. Remove
the engine and drill the firewall for the pushrod
tube using a drill and 5/32" (4mm) drill bit.
Step 6
Drill a 5/32" (4mm) hole in former 2 that corresponds
to the location of the hole drilled in the firewall.
Note: Make sure to drill the hole in former
2 far enough inside the fuselage so the wing
will not interfere with the pushrod tube.
Step 7
Test fit the throttle pushrod tube through the
firewall, through former 2, and into the fuselage.
Once satisfied with the fit, roughen the tube using
medium sandpaper. Slide the tube back into position
and use medium CA to glue it to the firewall.
