Last summer we were on a dump run and noticed an elderly couple chucking this gokart into the metal recycling bin. Wait what!?? So we backed up the truck and took it off their hands. We were warned that it had "transmission issues". After much fiddling, turns out it was not such a big deal, just a burned up snap-ring on one of the axles, so we "future-proofed" the drivetrain by welding on a retaining ring. Problem solved!
