I have an old Murray Ridding mower with a 12 HP Briggs some how gas is in the oil? I noticed this when cutting high grass it started smokeing white so I shut it off and the oil was really thin and smelled like gas. I changed the oil someone told me the float will stick in the carb when the motor is under heavy load. He recommended cleaning the carb. What should I do next and how can I keep this from happening again.

All wrong answers..... gas will get in the oil from a stuck float.....how? the breather tube..... the gas will flow up into the carb and flow through the tube, through the breather... into the oil.. its made even worse if the engine is caught on the compression stroke and the intake valve is closed just letting it go full flow into the crankcase.
I fix these problems all the time... just the other day, had the same thing, kinda funny since it was a 12horse briggs as well.
DO NOT RUN THE ENGINE!! like this, change the oil before you even try to run the engine.
You either have a stuck float, stuck inlet needle or some trash keeping it from seating, or a leaky inlet needle seat. May have sunk float (gets a pinhole and fills with gas and sinks).
Btw, I've prevented a couple from sticking again, by using marvel mystery oil in the gas to lube the float pin and all. Usually they don't stick, but if the engine is jammed around alot, they can.

If gas is getting into the oil, the probabilities are that the engine is breaking down. Yes, the float in the carburetor can stick, but that wouldn't cause gas to get into the oil. The two liquids are separated from each other in a sold engine. It sounds to me as though one of the cylinders has cracked, or some other part has. I'm not that familiar with the engine your talking about. I think you should take it to a lawn mower repair service.

Sounds like noone has the answer so I'd say take it to a small engine repair or buy a new mower, I suggest a WRIGHT they kick @#$! Good Luck

check the compression to make sure the oil rings on the piston are still oil tight.
