 Step 4
Attach the muffler to the engine using the hardware
provided with your particular engine.
Note: It may be necessary to rotate the end of
the muffler to point the stinger straight down,
away from the fuselage.
 Step 5
Check the tank and note which fuel line is vent and which
is attached to the clunk. Make a note of the line colors
and which they correspond to. Also note the direction
of the vent line inside the fuel tank so it faces toward the
top of the fuselage.
 Step 6
With the vent line up, slide the fuel tank into the fuselage.
 Step 7
Attach the vent line to the muffler and the line from the
clunk to the carburetor.
 Step 8
A Saito™ 4-stroke can be installed instead of a 2-stroke
engine. You will have to relocate the throttle pushrod to
line up with the throttle arm on the carburetor.
