looks like somebody cut apart and then broke off the flywheel so they could salvage the coils and points, I guess he didn’t have a flywheel puller 😯
I have seen that happen when an auto mechanic used a gear puller (which hooks to the edges of the flywheel) to remove the flywheel in order to work on the magnito. The flywheel came off, but the flywheel hub didn’t! . . ., 😀
Like the one Garry saw, some years ago when I didn’t know any better, I cracked off a flywheel on a 1958 35 Johnson using an automotive brake drum puller. I knew a flywheel puller was the way to go but didn’t have a suitable one and wanted it off NOW!
