Anyone know where to buy throttle shaft rebuild kits for these skis? I have read the thread about just sanding/filing and fixing the sticky throttle issue that way, but I would rather use all new parts. Here is my issue, I ordered 3 kits for the sbn 44 carb, and they do not work. The bushings are not the same as what is in these carbs. So I removed 2 of the bushings so far and then realized I ordered the wrong parts. So now I am stuck trying to find a throttle shaft rebuild for these carbs and I cant seem to locate anything other than the same sbn 44 kit I ordered previously. Goofy mistake with ordering but now I am needing some help locating the correct kit. Thanks.
