I'd be going back to the seller asking for a refund or something and using a different powerplant. Given the wear shown on the piston, I'd tend to agree with not doing a lot of work to this engine. It'll run I'm sure, but if the piston and cylinder are worn, ring sealing will suffer even if using new rings.
I have a Homelite 30cc engine laying around myself but I'm unsure of its condition internally. It appears to be low runtime and came off a weed trimmer. Has a Zama carb on it.
