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 3mmx10mm screws (4).
!
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 necessary to use a needle valve exten-
sion for the high speed needle valve. Make
this out of sufficient length 1.5mm wire and in-
stall 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.
