Central Machinery Engine

[kart for fun]

I have an old Central Machinery 6.5 HP/196cc engine (see pics) I bought from Harbor Freight over ten years ago but I've never used it. Now I'm rebuilding it and not sure what parts fit it. Does anyone know what connecting rod, cam, etc will fit this? Most kart part websites say "fits most 6.5 clones" or "fits most 196cc clones" but then they also say that those parts cannot be returned. So I want to make sure it's right. Any help or guidance is appreciated. And I don't really care to hear about it sitting on the shelf, or how I should know the answer. I don't or I wouldn't be asking. Also, if I removed the governor on it, what parts are an absolute must to replace to prevent damage at very high RPMs?

I think those old Lifan engines were dead nuts Honda clones.

I'm new to this, so excuse my elementary questions, but the engine parts on websites like gopowersports that say 196cc clones, that would be the right fit?

What about the piston, I took mine out and measured it and can't find one that's the exact size. How specific does it need to be? Mine is measuring 67.45mm wide, and the cylinder measured 67.95. The only pistons that I could find for sale are 68mm. The next size down was 57.4mm. Is the 68mm the right size, it's just not exactly 68mm?

I think the non hemi Predator 212 upgrade parts should fit that engine pretty well. Those Greyhounds aren't as well known as the newer Predators though.
