I'll add a little to what was posted above. Even after pulling/pinching the fuel line, there is usually enough fuel left in the engine to run a bit more. I connect the plug heat and flip the engine several times until it won't even pop any more. If you have an electric starter, a couple of seconds is all it needs to fully clear it out. Then, like lots of others, a little after run oil (air tool oil in my case), a few flips to distribute it and I'm done.
