Question about Craftsman 20 hp 42 in. Deck Lawn Tractor - CA Model
TRACTOR IS 3YRS OLD 18 HP MODEL. AFTER MOWING FOR ABOUT AN HR,, WHILE AT FULL THROTTLE, GOING UP HILL TRACTOR BLEW A LOT OF WHITE SMOKE FROM THE FRONT END. AND STARTED TO SPUTTER. SHUT IT OFF RIGHT AWAY. CHECK OIL LEVEL AND IT IS FINE. AFTER 5 MIN. RE-STARTED AND SEEMED FINE. NO NEW ENGINE NOISES. DROVE IT DOWN HILL AND ON THE WAY BACK UP HILL AT FULL THROTTLE, BLEW EVEN MORE WHITE SMOKE FOR THE FRONT. LET IT SIT, RESTARED AGAIN AND AT LOW THROTTLE AND DROVE BACK UP THE HILL AND PARKED IT. NEITHER TIME WAS THE MOWER BLADE INGAGED.
Start with making sure your oil lever is not over full. If it is it may be getting into the crankcase breather hose that goes to the carburetor hence the white smoke. Sometimes also you can blow a gasket in the breather system and it will do the same. Check for oil leaks in the breather system. Hope this helps. donnyb60

The oil breather hose connects from the crankcase to the carburetor. If the breather assembly on the crankcase gets plugged, oil can be pulled into the carburetor through the breather hose. Try removing the breather assembly from the crankcase and cleaning it in gasoline, followed with a blowout with compressed air. You can also just replace the breather assembly and hose.

You have fuel in your oil. Check the muffler to see if oil is blowing out of it. If so, I recommend a new carb versus installing new parts in an old one. With a tune up and new carb, you essentially have a new motor.
