12. Cut out the holes in the cowl with a high-speed rotary
tool and a small cutting bit.
❏
13. Cut the air opening in the front of the cowl as shown.
Note: Do not remount the cowl. The tank, fuel line and
throttle pushrod still need to be installed.
❏
1. Roughen the outside of the 11-3/4" [300mm] gray
pushrod outer tube with coarse sand paper. Fit the tube
through the firewall and the second former leaving 1/8"
[3mm] protruding from the firewall. Glue the tube to the
firewall and the second former in the fuse with thin CA.
❏
2. Arrange the stopper and tubes as shown in the photo,
then insert them into the tank. Tighten the screw to expand
the stopper, thus sealing the tank. Be certain the fuel line
weight (clunk) at the end of the fuel line inside the tank does
not contact the rear of the tank. Otherwise, the line may
become stuck above the fuel level and discontinue fuel flow.
Remember (or use a felt-tip pen to mark) which tube is the
fuel pick-up tube and which tube is the vent (that will be
connected to the pressure fitting on the engine’s muffler).
❏
3. Install the tank in the fuse. Fit the neck through the
hole in the firewall. Be certain the vent tube inside the tank
is pointing upward.
❏
4. Glue a 5/16" x 3/4" x 3" [8 x 19 x 80mm] balsa block
to the fuse to hold the tank in place.
