Hope someone can help,,just got this unit out from the shed a few months ago..been working on it and started to put it together,,,last bolt to tighten down was the fly wheel center but and it snapped off😥

The stend or threads are just about even with the flywheel…

Looked at the threaded stud and it was hollowed out about 1 inch from the start of the threads

Metal looks a little soft but a magnet barely attacks to it..

Any idea what I can do to snitch a nut down and hold the fwheel in place
