I had a piece of metal come off of the choke linkage and lodge down into the flywheel. It locked up the engine tight. I made sure I did nothing more, other than move the clutch by hand slightly to see if I could get it to turn.
You might want to pull the housing cover off of the motor and look around the flywheel to see if you can see anythings jammed in the flywheel. Just as Jim said, the magnets could of pieced off or something could've got jammed in there. Hopefully it's that easy and not an internal piston thats blown. If the clicking sound was bad enough I would be concerned that the piston rings took to breaking. And as Mike said, by draining the oil you might see metal in the oil or feel the metal shavings between your fingers in the oil. Hopefully that's not the case.
