I do not think plugging the stinger floods the engine as I stop mine all the time that way to make a quick adjustment and one pull on the starter and it fires right up. To me this is the very best way to do it. Other then running it out of fuel. I have never had a problem with running my engines out of fuel and most of the time is the way I stop them. I have some engines that I have done this for over 5 gallons with out any problems. When you run out of fuel there is still some oil in the engine as not all of the oil burns.
