I bought this fourwheeler from a kid. I have little mechanical expertise. I can swap parts but diagnostics is a problem area. Anyway I can hear what sounds like a tap or rattle in the top of the engine. To me it sounds like the piston might be hitting the top or something like that. But it for sure sounds like metal tinging off metal. Any suggestions?

Ok tonight. It's a high pitched kinda "ting" inside the top end. I will record tonight and post. Thank you.

Sounds like the valve lash. You can do the straw down the plug hole trick to maybe feel if the wrist pin is loose. The crank will move slightly but not the piston is there is slop. Something to try before removing the top end.
