mower was running and then stopped all of a sudden with a metal type sound. the blades were not engaged and it was sitting when this happened. i can turn the flywheel about 2 rounds counter clockwise and when i go back the other way after those turns it just stops. i can hear something hitting metal. doesnt sound like something is broke but like it hits a wall. I have tried to turn it with a breaker bar and it will not move past that one point. I have no idea what it could be at this point, any ideas?
b&S 17.5 flywheel stops

Something let loose in the engine sounds like. Check your oil?
Take the spark plug out then try spinning it, if spins like normal more than likely a valve issue. While the plug is out see if you can determine if the piston still goes up and down in the cylinder.

Outside possibility, magnet came loose in flywheel. More likely, threw a rod. Remove spark plug as said, stick screwdriver or dowel in plug hole and see if piston is moving when you turn flywheel. No, rod, yes maybe flywheel magnet.
