Unflood the Engine How-to
How do you know
when your engine is flooded? There are a number of things
that can cause the engine not to start.
The most common is a flooded engine. The characteristics
to look for are: no pop/ignition and a deeper tone when
spining over the engine.
What is a Hydro-lock condition. This is when the engine has so much fuel in the combustion chamber that it will not allow the starter to turn the engine over. To remove this condition tilt the helicopter over so the muffler is toward the ground. Now turn fan backwards about 1/3 of a turn. This will allow the fuel to run out of the combustion chamber and into the muffler.
