transfer the marks from the fuselage, that were
drawn onto the fuselage previously, onto the
cowl. Using a ruler and a pen, measure for-

!
5) While holding the cowl firmly in po-
sition, drill four 1mm pilot holes through both
the cowl and through the fuselage side.
Because of the diameter of the cowl,
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.

drill bit. Enlarging the holes through the cowl
will prevent the fiberglass from splitting when
the mounting screws are installed.

9) Install the muffler and muffler exten-
sion onto the engine and make the cutout in
the cowl for muffler clearance. Connect the
fuel and pressure lines to the carburetor, muf-
