MOUNTING THE NACELLE.
!
1) Put the fiberglass nacelle over the en-
gine and line up the back edge of the nacelle
with the marks you made on the wing then trim
and cut.
Because of the diameter of the na-
celle, it may be necessary to use a needle
valve extension for the high speed needle
valve. Make this out of sufficient 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.
!
2) While keeping the back edge of the
nacelle flush with the marks, align the front of
the nacelle with the crankshaft of the engine.
The front of the nacelle should be positioned
so the crankshaft is in
nearly
the middle of
the nacelle opening. Use the spinner backplate
as a guide. Hold the nacelle firmly in place us-
ing pieces of masking tape.
!
3)
Put the nacelle back over the engine
and secure it in place using thirty-two 3mm x
10mm wood screws. See picture above.
!
4) Install the muffler and muffler extension
onto the engine and make the cutout in the
nacelle for muffler clearance. Connect the fuel
and pressure lines to the carburetor, muffler
and fuel filler valve.
