COWLING.
1) Slide the berglass 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.
2) While keeping the back edge of the cowl 
ush with the marks, align the front of the 
cowl with the cranksha of the engine. e 
front of the cowl should be positioned so the
cranksha is in nearly the middle of the cowl
opening. Use the spinner backplate as a 
guide. Hold the cowl rmly in place using 
pieces of masking tape.
3) Install the muer and muer extension 
onto the engine and make the cut out in the
cowl for muer clearance. Connect the fuel
and pressure lines to the carburetor, muer
and fuel ller valve. Secure the cowl to fuse-
lage using the M3x10mm screws (4).
 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-
cient 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.
