I have a new 19.5 HP B & S single cylinder engine on a Craftsman mower. I turned it on its side to re-install the transmission drive belt, not thinking of the consequences. Now the engine is so flooded with oil it will not start and continually fouls the spark plug. It will ALMOST start, but not quite. How can I get the oil out so the engine will run? I've been cranking the engine without the plug and trying it with the plug, but still no start.
