Anthony, think it’s time to find a shop that specializes in frame straightening. I don’t believe that having one bearing hanger toed out will cause your problem. The axle will center itself between the two hangers. Suspect that the hangers are not in line, either not is the same horizontal or vertical plane. In other words, either one hanger leads or trails the other or possible one is higher than the other.
Call the shop first so the shop can explain what condition he’ll want you to bring the kart in.
