well, now I'm really distraught. I went to use the red inline spark plug testers just now, and the crank wouldn't turn. oil was gone! but there is no leak on the mower or the ground! on top of that, the air filter box is FULL of fuel and the air filter is soaked. I took it apart and disconnected the crank case breather hose (see pic), added some oil turned then turned the crank with my hand 1 revolution (it was almost impossible, but once it broke free, it was easy). I managed to start the engine, but fuel started GUSHING out the breather hose! I don't think that's normal. Should I give up and scrap this thing?
