To much oil ?

[Steelshipper]

I think this motor was overfilled with oil and used for several mows/hours! It will start but sputters and chokes and spits out a lot of smoke. What’s broke and needs replaced? Head gasket? Help! I’m not a mechanic!
It’s a 22.0 hp
724cc

If it was me I would change the spark plug run seafoam in the gas and pour some down the carb and let it set on the valves for a while they may be all carboned up.

Welcome, I would suspect the carb float needle may be leaking contaminating the oil causing it to be over full. Check to see if there is a gas smell to the oil, drain and refill to proper level with new oil if so, clean carb and replace float needle OR add a gas line shut off valve and use when engine is not running. When asking an engine question it is a good idea to post the engine model number.
