My craftsman lawnmower won't start it almost starts near the end of the revolutions.can anybody tell me what they think it is it has spark it just does not catch in time. I think it is because I turned it on its side and flooded the piston if that is so please tell me what I can do to get the oil out of the cylinder.

You can remove the plug, turn the engine over repeatedly, and the oil will blow out. Also you may have oil in the carb. And the oil filter. Let me know if this don't work.
