The slop is probably in the spindles where the bolt goes through to hold the skis on. We have a Scoot that almost steered it's self before we did a little mod job on it. I got two front hood bushings for an International 7600 truck (big truck like semi tractor) There is a little story on how I came across them, I sell heavy trucks & when I was at the parts counter asking for something like a bushing for the spindles on the Scoot the parts guy (Tim) said I think they use something like that on a 7600 & presto he was right. The bushings are 5/8 OD & 3/8 ID. Drilled out the spindle with a 5/8 drill & pounded in the bushings. I put on a new set of C&S Minis with a 3/8 bolt & the thing is like new again. You can drill out the skis & use a 3/8 bolt, should do the same trick. Try to find a set of plastic skis for it, its unreal how better the plastic skis work vs. the old steel ones. I can find the part number if you want, it might take another trip to the parts counter, let me know. Good luck, nothing better for the kids than "The Scoot".
