● 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 fi lter. Use a fi lter intended to be used with gasoline engines.
Metal fi lters intended for glow engine are too coarse and will not
screen out fi ner particles.
● Always fi lter your fuel by using an appropriate fi lter before putting
it into the airplane’s fuel tank.
● Gasoline is extremely fl ammable. Keep it away from an open
fl ame, 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 kill 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 mixing 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 mixing 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 suffi ce) 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.
● To avoid permanent damage to the electronic ignition system,
NEVER rotate the propeller on your DLE engine with the electronic
ignition system switched on and the plug not installed in the
plug cap.
