Barn find need help with ID and starting issues

[Krypto]

I found this at a jobsite. Took carb off tank off and drained oil. Cleaned tank and carb. New fluid . Checked plug and it has spark but it's dirty. Will get new one when stores open.

Looking to see if anyone can tell me the cc of this engine as well as any specs on it. It was free so just would like to get it running and have some fun.
