Great Planes Giles G-202 ARF - GPMA1315 - Manual (Page 10)

❏
1. Use thin cardboard or plastic to make templates
locating the firewall and forward fuselage.
❏
2. Slide the cowl over the engine and fuselage. Install the
spinner backplate and center the cowl 3/32" to 1/8" [2.5mm
to 3mm] behind the spinner backplate. Tape the cowl in
position and place four marks (two on each side of the cowl)
for the cowl mounting screws using the templates.
❏
3. Drill a 3/32" [2.5mm] hole through the cowl and fuse at
each mark. Remove the cowl and enlarge the holes in the
cowl only to 1/8" [3mm]. With the cowl removed, apply a
couple of drops of thin CA to the cowl mounting holes in the
fuse to harden the wood. This will prevent the holes from
stripping out during flight. After the CA has cured, attach the
cowl to the fuse with four #4 washers and four #4 x 5/8"
sheet metal screws.
❏
4. Remove the cowl and use a piece of thin cardboard or
plastic to make templates for the cutout in the cowl for the
glow plug, needle valve and exhaust. Tape the templates to
the fuselage side, accurately indicating the position of the
cylinder head.
❏
5. Remove the engine and install the cowl. Transfer the
glow plug, needle valve and exhaust holes from the
templates onto the cowl.
❏
6. Remove the cowl and templates, then remount the
engine. Cut out the holes in the cowl, then test fit it to the
fuselage. You may want to make the cuts slightly smaller
than the template outline to allow for adjustment. Adjust the
position and size of the holes as needed.
Note: There are three holes in the fuel tank stopper but only
two are used for this model. Do not puncture the third hole
in the stopper.
❏
1. Push one short aluminum tube and one long
aluminum tube through the rubber stopper until 1/2"
[13mm] of the tubes protrudes from the front of the stopper.
Slide the large cap onto the front of the stopper, and the
small cap onto the back. Insert the stopper screw into the
center hole in the front cap, then screw it through the stopper
into the aft stopper cap. Just start the threads in the aft cap
or you won’t be able to insert the stopper into the tank.
❏
2. Push one end of the silicone pickup tube all the way
onto the clunk, and the other end all the way onto the short
aluminum tube. Bend the long aluminum (vent) tube upward
at about a 45º angle, being careful not to kink the tube.
