Kohler Rialta toilet

[morkor]

I have a Kohler Rialta K3386DA one piece toilet. It flushes and drains very slowly so that its not usable. I have replaced the flapper with a original Kohler one and that did not help. I have been told that replacing the drain valve will help. I have tried to find one locally (including Ace Hardware) but they do not have the right one. The drain valve in my toilet does not drain through a hole in the bottom like most do . . . but drains through a hole at the front of the tank. I have never seen one like locally. Any ideas or suggestions? Thanks Morry.
