Probably just needs a cleaning. The spring also can get mangled and is replaceable. 50 cents for that part.
Could also be that the gears were just in the wrong position and just grind that one time, may never happen again.
Or it could be that the bolts holding the starter on have come loose. Tighten it all up and see what happens.
