What stands out to me is that you are having to put a lot of steering into the right hand corners but the kart is so aggressive on the left hand corners that you are counter steering most of the time. This would likely be due to a cross weight issue or an issue in the steering alignment. The most common cause would be that the steering shaft is bent or was not centered properly when the toe was adjusted. If the steering shaft is slightly off to one side when you “Square up” the toe it will cause the steering to be lazy one way and aggressive the other. It only takes a small offset to have a big affect on the cornering. Other issues that can cause this are having different tire pressure on different corners or having a worn out tire compared to other tires. The circumference of the worn tire would be less and would change the weighting of that corner.
