use a petroleum based 2-cycle motor oil like Lawn Boy All Season – Ashless, Generation
II oil for the break-
in period. Break-in should be considered about the first 3-5 gallons you run the engine. A
high quality synthetic 2-cycle oil is recommended for optimum performance and a longer
engine life. Synthetic 2-cycle oils leave fewer combustion byproducts than natural oil
which can foul the engine and exhaust ports, resulting in reduced performance. Synthetic
oils also reduce friction and provide more fluidity at low temperatures.
● Do n
ot install your throttle servo or kill switch servo inside the engine compartment.
Doing so could cause radio interference. Install all electronic radio devices as far away
from the engine as possible.
● The throttle and choke pushrods should be non
-metallic.
● If the engine is not to be used for more than a month, drain the
fuel tank and remove
any fuel from inside the carburetor. Do this by running the engine at idle until it quits by
running out of fuel.Keeping gasoline inside the carburetor over an extended period of
time will damage the diaphragm valve and clog passages inside the carburetor. Due to
the carburetor being more complicated than those used in glow engines, keep the fuel
clean by using a fuel filter. Use a filter intended to be used with gasoline engines. Metal
filters intended for glow engine are too coarse and will not screen out finer particles.
● Always filter your fuel by using an appropriate filter before putting
it into the airplane’s
fuel tank.
● Gasoline is extremely flammable. Keep
it away from an open flame, excessive heat or
sources of sparks.
● Do not smoke near the engine or the fuel tank.
● This engine was designed for use in a model aircraft. Do not
attempt to use it for any
other purpose.
● Always install an ignition system ki
ll switch on the aircraft used.
●
Do not install your throttle servo or kill switch servo inside the engine compartment.
Doing so could cause radio interference.Install all electronic radio devices at least 12”
[305mm] away from the engine.
● Caution:
Running the engine with a lean gas mixture will cause the engine to overheat
and burn the electrode of the spark plug. Pay close attention to the High-speed Needle
adjustment. Running the engine with the proper gas mixture will cause the spark plugs
to appear yellow at the ignition point.
● For optimum performance please use fresh or recently purchased
93 octane gasoline
(87 octane gasoline will suffice) with a 30:1 gas/oil mixture.

● Excessive running of the engine at idle speed can result in a
seriously carbonized
spark plug.
● Keep the surface of the engine clean to ensure proper heat
dissipation. Ensure proper
cooling/ventilation around the cylinder with adequate air exhaust.
