That really looks like a low milage engine. Don't re-use the studs, they streach. That crank is junk, don't even think about it. You have the worst type of cylinder head, we call it the American one, which makes perfect sense, considering. I would re-use the cylinder (if its the 12hp one) but bin the head and piston.

Are you wanting to restore this engine as exact original or fix some known issues to make it go better?

I'd like to keep it mostly original but was planning on a bigger top end for more power, and a DC ignition system for led headlight.

Flywheel off and stator plate out. The woodruff key was rusted into the flywheel cover so it took some effort and finally popped. There appears to be a lot of "salt" inside this area specifically coming from the wires on the stator plate as pictured. Didn't get a shot of the salt inbetween the stator plate back and the electrical coils mounted to the plate as that seemed to be where most of this salt is coming from. This makes me think the stator plate probably needs replacing due to corrosion.

BTW is it me or is that fly side seal brand new? More and more confirmations this engine has seen practically no use.

Flywheel magnets hold a 17mm wrench fine. Gonna clean out the rust and reuse this part. woodruff key junked.

You can see a ton of salt in the hole of the stator plate where the wires come out. there is a lot of salt behind the electrical coils on the front side.

It looks like that stator can be cleaned up. Try compressed air and a tooth brush to get rid of the "salt". Are the wires brittle? If so, it just needs to be rebuilt. ScooterMercato or Gickspeed will rebuild it and from pictures they both do a fine job.

I rebuilt my own and then checked the ohms to ensure it was working. And it does! Check out Getting an old Vespa (P200) back on the road about three quarters down the first page. I don't know how to link to the exact post.

Here is close up of the corrosion salt on the coils..

I'd clean it up with a wire brush, toothbrush, electric spray, compressed air, etc. But what do I know... I'm all for saving what you can. You might want to check the impedance of the coils. Stator Values Wiki. And if the coils are good, then clean it up!
