Flooded Engine
If the engine fails to start after repeated
attempts, it may be flooded with excess fuel.
To clear a flooded engine, leave the engine
stop switch to (RUN) and push the
choke knob to Fully OFF ( ). Open the B
throttle fully and crank the engine for 5
seconds. If the engine starts, quickly close
the throttle, then open it slightly if idling is
unstable. If the engine does not start, wait
10 seconds, then follow the Starting
Procedure.
