TROUBLESHOOTING
8.1 Diagnosing and starting a flooded engine
A flooded engine can be identified by the smell of unburned gasoline coming from the exhaust pipe, or
by periodic weak firing and puffs of black smoke during starting attempts. If you have a flooded engine,
follow the procedure below:
•
Remove the spark plug and thoroughly dry it. (Note another indication of a flooded engine is a spark
plug that is dripping with gas).
•
With the spark plug removed push the starter button for a few seconds while holding the throttle in
the full-open position. This will remove excess fuel from the engine.
•
Install the dry spark plug, and start using the normal procedure.
WARNING!
Ensure you have placed the spark plug cap away from all fuel sources before pulling the
starter cord or a fire could occur!
WARNING!
Do not use a flooded engine procedure whereby you hold the throttle wide-open and then
attempt to start the engine.
If the engine were to start, the prop would rapidly spin to full RPM and damage or injury would most
likely occur!
