I have a Huskee riding lawnmower with a Briggs and Stratton engine that has fuel in the oil what would cause this and how can I fix it?

This is a common problem when you have a full tank of gas and when the piston stops at a certain spot a siphonin action brings gas into the cylinder and pass the rings, when you get enough gas in oil engine will smoke....To stop this purchase a in-line shut off valve from tractor supply co. Leave valve off when not in use.Hope this helps
