6.5 HP Briggs and Stratton powered mower. It ate the plastic bit between the pull cord and the flywheel on the top so I replaced it. Pulled the plug and spun the blade and it felt a bit chunky. Put the plug back in and gave it some pulls. Still a little chunky and then I think it broke the plastic again. I wonder if I might have a bent valve or something. Thoughts?
Edit: that is a turbine powered mower. Not mine.
