COWLING INSTALLATION.
Trim and cut.
Trim and cut.
Machine Screw M3x10mm
3) Install the muffler and muffler extension
onto the engine and make the cutout in the
cowl for muffler clearance. Connect the fuel
and pressure lines to the carburetor, muffler
and fuel filler valve. Secure the cowl to fuse-
lage using the 3x10mm screws to tighten the
screws.
2) While keeping the back edge of the
cowl flush with the marks, align the front of
the cowl with the crankshaft of the engine. The
front of the cowl should be positioned so the
crankshaft is in
nearly
the middle of the cowl
opening. Use the spinner backplate as a guide.
Hold the cowl firmly in place using pieces of
masking tape.
Because of the size of the cowl, it may be nec-
essary to use a needle valve extension for the
high speed needle valve. Make this out of suf-
ficient length 1.5mm wire and install it into the
end of the needle valve. Secure the wire in
place by tightening the set screw in the side of
the needle valve.
1) Slide the fiberglass cowl over the
engine and line up the back edge of the cowl
with the marks you made on the fuselage then
trim and cut as shown.
