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.

be smooth. If acceleration is not smooth, adjustments to the carburetor may be
necessary (see Adjustment of the Engine).
