No clue what I'm doing... No start...I'm back and I need help to make it right.

Also... Have you ever seen one of these I just got it and want to get it running the kid that sold it to me thought it to be blown.. But it started so I don't think that's what the problem. Is I'm cleaning it as we speak so I can take and tear it down and relube everything. Any ideas on what it is or maybe what I should plan on.
Looks like a CAG engine with a saw jug, so it will be a piston port. Post a couple more pictures of it when you take it apart and I'll let you know.
