Flooded engine
If the engine fails to start after several attempts, it is probably flooded. This occurs when too much
fuel is drawn into the engine and the spark plug fails to ignite it. The smell of gasoline is often evident
when the engine is flooded. Troubleshoot a flooded engine as follows:
1. Look for gasoline overflowing from the carburetor or overflow hose. If gasoline is evident, the
engine is flooded and/or the float in the carburetor bowl is stuck. If the carburetor float is stuck,
remove and repair the float assembly Shift the transmission into neutral.
2. Check that the chock knob is fully closed (pushed in).
3. Open the throttle fully and hold in this position. Then start the engine firmly through its entire
stoke ten times to clear the engine. Close the throttle.
4. Release the hot start lever as soon as the engine starts.
5. If the engine still does not start, refer to Engine will Not Start this chapter.
