Gorilla Winches with Blue Steel Rope?

My friends KQ 300 starts fine and runs, as soon as you put it in gear and try to accelerate its bucks and farts like crazy, not moving... I cleaned carb and it worked good for 1 day... now back to same problem.... could it be such as a bent valve????

This is something I'm extremely curious about. Has anyone ever attempted to buy a quad (or any other vehicle) from an impound lot? I've always wondered if this could be a bargain, or a waste of time. Google searches do turn up some helpful results. Looks like the state of NJ holds auctions online which I'd be a bit hesitant about.
 
My online searches haven't really turned up any results of anyone buying an ATV this way. I'd be really curious if anyone tried this, or knows someone who has. I've actually found a couple pages with online auctions for my state, but none had ATVs.

I am in the process of puting it back together after replacing the DPS gearbox.
The manual I have states that it will need to be flashed by a dealer. Is this still true?
Also , I have a mystery bolt That I cannot remember where it goes. M6x 70 or so.  Hex head with a flat washer.I will try to attach a pic.
Pic is no go for now....Cox issue I will try again later
TIA
