5. Rapidly flip the propeller until the engine starts. If the engine does not

start, repeat the steps 1-4.

6. After starting, let the engine idle for two to three minutes. Open and close

the throttle until the engine runs smoothly at idle and at full throttle.
Acceleration should also be smooth.

Safety Warnings:

For manual starting, make sure the propeller is properly adjusted on
the propeller shaft to allow you to rotate the flywheel past the ignition
coil at the highest possible speed during starting. Flip the prop rap-
idly from the point where you can first feel the compression.

Warning: Gasoline is volatile and flammable. Gasoline should be
stored in an approved container, away from heat or open flames. Do
not smoke near gasoline. Use caution when transporting gasoline
and take precautions when fueling your engine.

Starting With Optional Spring Starter  (FJIG1086)

1. With the ignition OFF, close the choke plate on the carburetor and open

the throttle slightly from the idle position.

2. Rotate the propeller slowly about 10 to 20 times (more in Winter) until fuel

begins to move to the carburetor. (Swing the prop one-half turn to move the
piston from top dead center to bottom dead center, and then back to top dead
center repeatedly. Opposite rotation can also prime the carburetor but will not
be possible when using the spring starter.)

3. Turn the ignition ON. Hold the propeller, turn it clockwise 360° (one rota-

tion) and let it go. Turn the choke lever to the OPEN position after you hear
an initial firing and the engine stops. You can squirt gasoline directly into
the carburetor if the engine does not fire. Repeat steps 1,2, & 3 above, as
necessary.

Starting With Optional Electric Starter (Onboard type or External type)

1. With the ignition OFF, close the choke plate on the carburetor and open

the throttle slightly from the idle position.

2. Turn the propeller with the starter for a few seconds until fuel begins to

move to the carburetor.

3. Turn the ignition ON. Turn the propeller with the starter.

4. Turn the choke lever to the OPEN position after you hear an initial firing and

the engine stops. You can squirt gasoline directly into the carburetor if the
engine does not fire. Again, turn the propeller with the electric starter.
