Hi, need some help. I'm have a craftsman riding mower that has a 25hp Kohler pro (model # CV730-0029) which has the notorious Nikki carburetor (Kohler p/n 24 853 102-S). I searched on partstree and they want about $1100 for oem carburetor (tractor's not worth that), sooooo, in light of that, does anyone have a source for a rebuild kit or what are your thoughts about an aftermarket carb from Amazon? I find some of those deals on Amazon a little sketchy. Appreciate any help, Gpooh68
