David, Sounds like the mower is being tipped on it's side before or during cranking...if not, check the crankcase breather, this is not the air filter but it should be a cover secured with two small bolts near the exhaust. Once removed make sure it is not clogged.

David, Make sure that you have the correct amount of oil in the engine. Too much will cause this. I think you will find this is blow by the rings. Sounds like your engine may have some age on it.
