Are the parts the same in a kohler k90 and a k91, I know they should be. kohler just changed the way they lettered the engines after the k90. I am in need of a coil for my k90, it quits when it gets hot. I think I need a 220435 but don't want to spend the $40 without being sure.
If anyone here has one let me know I would rather buy here than e-bay.
