Starting Procedures
When starting the engine the fi rst time and during break-in it’s
recommended that you run the engine without the cowling. Also,
for safety reasons do not adjust the carburetor while the engine
is running.
There are two recommended ways to start the DLE-20:
A. Manual Starting
Note: When hand starting the DLE-20, use a thick glove or heavy
duty starter stick to protect your hand.
1. The propeller should be installed on the drive washer at the one
o’clock position and at the beginning of the compression stroke
so that it’s comfortable to fl ip it through compression.
2. Have someone help you hold the airplane while you start the
engine.
3. Switch the ignition to ON, close the choke on the carburetor and
open the throttle slightly from the idle position.
4. Flip the propeller counter clockwise several times briskly, until a
popping sound is heard. This indicates that the engine is fi ring.
5. Move the choke lever to the OPEN position.
6. Set the throttle to a high idle. Set the propeller so that it is at
the beginning of the compression stroke.
7. Flip the propeller through compression rapidly. If this is done
properly, the engine will start after several brisk fl ips of the
propeller.
8. After starting, let the engine idle for 30 to 45 seconds. Open
and close the throttle slowly until the engine runs smoothly at
idle and at full throttle. Acceleration should also be smooth. If
acceleration is not smooth, adjustments to the carburetor may
be necessary (see Adjustment of the Engine, page 12)
9. If your engine does not start, repeat steps 2-8.
