Evolution Engines EVOE116GX2 - Manual (Page 4)

mounting the engine
Most model airplane designs make provision for an engine
mount. It is extremely important that the engine mount be
securely attached to the airplane’s firewall and that the engine
is securely attached to the engine mount. Follow the instructions
included with the airplane for mounting the engine. The engine
should be fastened in place to the firewall with 4 screws. Use
¼” or 6mm screws. If you decide to fasten the engine using a
flexible motor mount, always choose parts with enough solidity
and strength. Make sure all screws are tightened and regularly
check that they remain tight and in good condition.
Important: Air is necessary to cool the engine during operation.
Make sure that sufficient air circulation through the cowling is
provided.
Throttle Linkage
Carefully attach the throttle linkage to the engine using a ball
link on the carburetor. Make sure that the linkage is free to
operate from low throttle to high throttle and confirm that low
throttle setting on the transmitter closes the carburetor butterfly
to the low idle position. Adjust the length of the pushrod until
full throttle opens the throttle fully, while low-throttle, low trim
completely closes the butterfly.
Attaching the Fuel Lines
Use medium gasoline-compatible fuel line in the fuel tank as
well as the supply line to the engine.
Selecting a Suitable Propeller
The Evolution ® 116GX2 has been designed to generate maximum
power at 5800–6300 rpm, according to the type of exhaust used.
If you wish to utilize the maximum power output, choose a
propeller, which will allow the engine to reach these revolutions,
or slightly lower revolutions. (The engine will unload in the air
depending on the aircraft speed and propeller selected.)
Suggested Propeller Dimensions
Two-blade propellers:
28x10-14, 30x10-12, 32x10
We do not recommend using propellers that allow the engine to
reach more than 7500 rpm on the ground.
control Jet System
Your engine is equipped with a unique system enabling improved
acceleration from idle to high speed. This system allows the
mixture to be controlled while the throttle valve is opening. It
will lean the mixture at low rpm and at idle. Conversely the
mixture will become richer as the throttle is opening. This system
provides better acceleration to high speed and maintains a
stable idle.
This system was developed for the Evolution 116cc engine. It
is recommended that you do not change the mixture control
leverage.
