Deere mower with single cylinder engine? Make of engine? Is the oil level too high?Does the oil feel thin and smell of gas? If so, you are sucking the oil/gas mixture into the combustion chamber and the oil is causing the knock and the white smoke.

Single cylinder Briggs engine. I see a new question, please respond to this one! Does engine run clean for just a short while and then starts to smoke?

Please respond to this question and not open new requests!

With no other problem, you can have a bad head gasket, letting oil be sucked into the combustion chamber between the block and the pushrod cavity. You would need to remove the head and replace the head gasket.
