I understand it's a vacuum operated petcock. But just cranking the engine won't in my opinion open the petcock. Can't hurt to try putting an outside vacuum on the petcock to rule out this possible problem. Besides, all this cranking those plugs should be soaked if the fuel is flowing.

That's one thing that has me wondering. I'm not getting the "flooded" smell, the plugs smell like gas but aren't wet.
