● The throttle and choke pushrods should be non-metallic.
● In case 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. Because the carburetor is 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 engines 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 on/off switch on the aircraft used.
● 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 make the spark plugs
appear yellow at the ignition point.
● For optimum performance please use fresh or recently purchased
87– 93 octane gasoline with a 30:1 gas /oil 2-stroke (2-cycle) 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.
● 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.
● If you choose to use the optional TX activated gas engine kill switch
(DLEG9205) it is strongly recommended that you install the TX
activated kill switch between the with a manual on/off switch and
the ignition. The manual on/off switch provides an added safety
feature in the event the TX activated kill switch does not function
properly. This is especially important during the starting sequence
as it requires the manual on/off switch to be in the ON position
before ignition can occur.
