Step 1.
When installing the Zenoah
®
G-23 Gasoline engine,
there are two things that are important to keep in mind. First,
provision for a "kill" or "shut-off" switch is a requirement for
safety. Second, the G-23 engine's weight may require tail weight,
such as a battery, being moved rearward or even lead weight
added to the tail. Otherwise the aircraft could be nose-heavy and
unsafe to fly. Be sure to read Section 20, "Balancing the Aircraft,"
and make sure the aircraft is balanced before any attempt to fly.
Step 2.
Seal the round motor mount dowels and firewall by
mixing approximately 1 ounce of a 50/50 mixture of 30-minute
epoxy and rubbing alcohol. Brush it on the entire firewall area
and wood motor spacers to seal them from fuel. Allow the epoxy
to cure completely.
Caution:
Do not get epoxy into any of the predrilled holes.
Step 3.
After the epoxy has dried, prepare to mount the Zenoah
G-23. First, locate the 4 mm x 25 mm flat head machine screws.
Step 4.
Mount the engine/dowel standoffs to the firewall using
the 4 mm x 30 mm machine screws, nuts, and washers.
Note:
It will be necessary to insert a long piece of music
wire (not provided) through the fuselage/firewall and place
a blind nut on the wire so it can be guided into position
for the bottom screw hole in the firewall. Repeat for the
other holes.
Step 5.
Instructions on throttle linkage installation and cowl
installation will be covered in Sections 15 and 16.
