COWLING.
1) Slide the fiberglass cowl over the en-
gine and line up the back edge of the cowl with
the marks you made on the fuselage then trim
and cut.
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 crank-
shaft is in
nearly
the middle of the cowl open-
ing. Use the spinner backplate as a guide. Hold
the cowl firmly in place using pieces of mask-
ing tape.

Because of the diameter of the cowl, it
may be necessary to use a needle valve ex-
tension 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. Se-
cure the wire in place by tightening the set
screw in the side of the needle valve.
