Mounting the Engine
Most model airplanes include an engine mount. It is
extremely important that the engine mount be securely
mounted to the airplane’s firewall and that the engine
is securely mounted to the engine mount. Follow the
instructions included with the airplane for mounting the
engine.
Important: Before each flying session, check that all
engine mounting screws are securely tightened.
Installing the Muffler
WARNING: Read and follow all instructions and
precautions before use. Failure to do so could
result in product malfunction, damage and injury.
WARNING: This product can become extremely
hot when in use, which could lead to burns.
NOTICE: Only use this product with parts
specified in the product literature.
Using the included muffler mounting screws and lock
washers, attach the muffler with the included hex
wrench. Be sure the lock washers are placed over the
screws and that you securely tighten both screws with
good torque.
EVO Team Tip: Because of the small size of this engine
you will need to loosen the two engine backplate screws
that hold the remote needle valve mount to the engine in
order to insert the rear muffler mounting screw. Once you
have inserted the muffler mounting screw into the engine
don’t forget to tighten the remote needle valve mount to
the backplate.
EVO Team Tip: A quick note about muffler gaskets. One
of the many causes of a muffler coming loose is that the
paper gasket material becomes crushed by the muffler
mounting to the engine, and this leads to the screws
actually loosening on their own. As the two surfaces
(engine crankcase mount and muffler mounting face)
are both machined surfaces there should be little, if any
leaks between these two surfaces and you may choose
to mount the muffler without the included gasket.
Important: After five runs, retighten the muffler
mounting screws. Also, tighten the muffler thru-bolt at
this time as well—loosen the lock nut on the back of the
muffler, tighten the thru-bolt via the screwhead at the
front of the muffler then retighten the lock nut at the rear.
Securely tighten all engine mounting screws and recheck tightness
before each flying session.
The muffler mounting accessory package includes mounting screws
(2), lock washers (2), muffler gaskets (2) and an L- wrench.
Attach the linkage to the throttle arm.
