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 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 on/off switch on the aircraft used.
●
Caution: Running the engine with a lean fuel mixture will cause
the engine to overheat and burn the electrode of the spark plugs.
Pay close attention to the High-speed Needle adjustment. Running
the engine with the proper fuel 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 fuel/oil mixture.

●
Excessive running of the engine at idle speed can result in
carbonized spark plugs.
●
Keep the surface of the engine clean to ensure proper heat
dissipation. Ensure proper cooling/ventilation around both
cylinders 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.
●
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 on/off switch and the
ignition. The 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 on/off switch to be in the ON position before ignition
can occur.
