Thanks, FBM! I'm getting this one on Saturday. It's for a parent at school who "contracted me" to get them a kart for Christmas for their kid. I'm paying $300. The description says "yerf dog go-kart has 6.5 horse engine with live axle (posi. trac) front and rear suspention very strong motor,theres a problem with the carb or throtle it runs strong for 10 min.then it will die" I have a new Predator that I'll put on it and it should be a quick flip. Gotta keep the parents happy!
