Lock up

[wan37]

I would pull every covers look inside for marks. Sometimes you get lucky. Gear lose or keyway came out. Then it really sounds like wrench is correct to lean. Piston rings or bearings somewhere. Pulling apart is necessary. Pulling everything’s is really my first choice rings or cylinder , bearings. I’m sure you will find the problem. Post things and pictures of things ,members will help you. If you have questions.

You DO NOT want to use full synthetic oil when breaking in a china girl motor.

Why

Synthetic is too slippery to get a good seat on the rings.

That looks like it could be easily saved..... Light honing/sanding and new rings.
