3. Switch the ignition to ON, close the choke plate on the carburetor and open the throttle
slightly from the idle position.
4. Use your electric starter to turn the engine over for several seconds, until a popping
sound is heard. This indicates that the engine is firing.
5. Move the choke lever to the open position.
6. Set the throttle to high idle and use your electric starter to turn over the engine until it
starts.
7. 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).
8. If your engine does not start, repeat steps 2-7.

and be sure to have the spark plug firmly plugged into the ignition wire.

The high voltage from the ignition can cause bodily harm, especially when
checking for spark in this manner.
