I have cleaned carburetor, changed spark plug, got new gas, and changed flywheel key and adjusted magneto spacing. The engine runs cuts entire lawn but sputters instead of running smoothly. I also put stabil in gas.

As a rule when a engine starts to run rough after it warms up the first thing I look for is a tight valve. Another thing that effects a warm engine running rough is a coil going bad. You need to look for something temperature related. Cleaning carburetor, spark plug, gas, flywheel key and mag spacing wouldn't have anything to do with the engine temperature.
Three different spark plugs with same result. Could the magneto be bad?
