If you have max ackerman and toe out when the steering is centered and then you turn the steering full lock you’ll basically get the front wheels pointing radically different directions. With a bunch of ackerman the outside wheel will turn in through about 75% of the steering range and then it will reverse direction while the inside wheel will continue to turn sharper in the direction you are turning the steering wheel. The end result will be around 2 to 3 inches of toe out at full lock and no kart will roll free in that condition.
When you made all the adjustments to the front end you nullified a lot of the effect described above so the kart will roll easier. The key thing to keep in mind is that you will never use full lock turning into a corner on the track unless your front tires are bricks and you have a huge understeer condition.
