Flooded Engine
If the engine won't start after several pulls on the
starter rope the engine is probably flooded.
To clear a flooded engine:
1. Move the throttle lever to "STOP" and turn off the
fuel valve.
2. Remove and dry the spark plug. When re-installing
the plug, thread it in by hand until it seats. Then
tighten it an additional l/8- l/4 turn with the spark
plug wrench to compress the washer.
3. Move the throttle to "HI", turn on the fuel valve
and repeat steps 3-5 under "Starting the Engine".
Stopping the Engine
1. Release the roto-stop lever.
SDA and SDAW TYPES: Release the drive clutch
lever.
2. Move the throttle lever to "STOP" and turn off
the fuel valve.
