a flooded engine doesnt just mean fuel in they cylinder. thats a "top" flood.

Too much fuel can also build up in the base (bottom of carb inlet) and in the exhaust pipe. Thats a "base" flooded motor.

To clear a base flood, pull the glow plug as before, remove the fuel inlet line on the carb and pull the starter with the model at an angle which will let fuel drain out of the muffler.

A base flooded motor will be very hard to pull over and untill cleared will not let a motor start. I have had a few motors get base flooded and I got frustrated trying to start them....only to come back an hour or so later and have the motor fire right up (fuel evaporates eventually)

If you have a motor that was starting a running...fail to start...always assume its flooded before messing with needle adjustements or anything else. try to clear the flood (again, tip the model so that fuel can drain from the muffler) and try again.
