Engine Briggs Stratton V-Twin full with petrol

Moin people! I have a KTS (MTD) mower with a Briggs&Stratton Intek series 7 200 engine with 656cc. So, today I wanted to mow.. he jumped normally, after a short time he began to stutter, squirted black.. went out, gasoline came out of the intake front. The good part pushed into the hall, hood off.. whole engine stinks of gasoline. Oil measuring rod pulled, clear broth in. Looking at the tank, half empty… a few minutes ago the edge was full. Spark plugs turned out, comes out Gasoline out. Spark plugs completely wet. Valve lid degraded, gas runs out… Turned on the engine, can’t be turned around. So… can this be something that said goodbye in my carburetor that he has let too much gasoline through? I have ordered 5l motor oil only for flushing, new oil filters, spark plugs… hope you can still save it. :-/
