accidently put kerosene in my walk behind lawn boy mower..(5hp briggs and stranton) the mower starts and stays running but it doesnt seem to have any power to it. is there anything i can run through the engine , fuel line , carb to clean it out more ? or have i ruined my mower?

HAven`t ruined anything even might have help clean carbon off piston but drain fuel and put in freash fuel and would be a good idea to change oil
