I agree with the method of shutting down an engine by reducing the fuel supply to less than the minimum necessary to run. If te idle is set correctly you should be able to completely shut off the fuel supply. From a personal standpoint I can see no valid reason for loading an engine up with as much fuel as possible in order to flood the engine.

The thought of having (even if it did indeed occur) a bunch of loose carbon deposits that had been disturbed by the flooding/shut down process floating around the top and bottom end the next time it started bothers me greatly.
