GAS ENGINE INSTALLATION
177.
Prepare the stopper assembly by placing small amounts of
solder on the end of the tubes shown. This will help keep the
fuel lines secure when installed.
Use hemostats to act as a heat-sink to
avoid melting the rubber stopper.
178.
Cut a piece of fuel tubing that will result in the end of the
clunk being 5 inches (127mm) from the back of the aluminum
plate. Secure the tubing to the clunk and stopper using thin
wire. This will keep the tubing from sliding loose inside the
tank. Make sure to use the clunk supplied with your engine.
A second clunk can be installed to provide
a line to fuel/defuel your aircraft.
180.
Mark the lines from the tank so the fuel lines can be identifi ed
from outside the tank. Tighten the screw in the stopper using
a #1 Phillips screwdriver.
Check that both clunks can move freely inside the tank.
If not, adjust the tubing from outside the tank so they can
move freely to ensure consistent fuel flow to the engine.
179.
Insert the clunks into the tank. Install the larger clunk, then
the small clunk.
181.
Secure a 5-inch (127mm) fuel line to the fi ll line of the tank.
The overfl ow line can be attached to the vent, as well as the
remaining tubing to the clunk line that will eventually attach
to the carburetor. Tie wraps can also be used to secure the
fuel lines as an alternative to wire ties.
185.
Attach the engine to the fuselage using four M5 x 20 socket
head cap screws and four M5 washers. Place a drop of
threadlock on each screw before their installation. Tighten the
screws using a 4mm hex wrench.
182.
Attach the engine to the engine mount using four M6 x 100
socket head cap screws, four M6 fl anged nuts and the four
aluminum standoffs. Apply a drop of threadlock to the end of
each screw before threading the nut onto the screw. Tighten
the hardware using a 5mm hex wrench and 10mm nut driver.
184.
Secure the tank to the engine mount using hook and loop
straps. A thin piece of foam between the tank and mount
will prevent the tank from sliding when installed inside the
fuselage.
186.
Secure the ignition module to the fi rewall using 4-40 x 1/2
inch or M3 x 12 sheet metal screws. Make sure to position
the module so it does not interfere with the engine or
installation of the cowling.
183.
Fit the tank into position. Connect the line from the clunk
included with the engine to the carburetor. Use tie wraps on
each end of the fuel line to prevent it from disconnecting.
