Section 6: Installing the Engine

Step 3
Position the engine onto the mount, sliding it between the
mount and the mounting plates. Slide the two remaining
8-32 x 7/8" bolts through the front holes in the mount.
Thread the two remaining 8-32 locknuts onto the screws.

Step 4
Start by tightening the bolts at the rear of the engine. Once
they are snug, slide the engine so the distance from the
firewall to the front of the propeller drive washer is
7
4 / " (113mm). You want to have tightened the front and
16
rear bolts equally as the plates act as a clamp to hold the
engine in position.

Step 5
5
Locate the 15 / " (397mm) throttle pushrod wire. Slide a
8
clevis retainer onto the clevis. Thread the clevis onto the
pushrod wire until the wire can barely be seen coming
through between the forks of the clevis.

Step 6
Slide the pushrod wire through the tube pre-installed in
the fuselage. Attach the clevis to the throttle arm, then
slide the retainer over the forks of the clevis. This will
prevent the clevis from opening during flight.
