Check oil level, if ok remove spark plug and crank engine. If it spins then likely "starter stall" due to valve lash out of tolerance. BS OHV engines require periodic adjustment of the valves.
If oil level is excessively high then likely engine has hydro-locked... the cylinder(s) are full of oil/fuel due to a stuck carburetor float.
