PlumberFilter: I have turned a big toilet leak into a small one. How can I stop it entirely?

I have replaced the flapper, flush valve, overflow tube, spud washer, bolts, and gaskets. A big leak (spontaneous refilling every 1-2 hours) has become a small leak (2" drop in water level in 12 hours). Now what should I do to make it stop entirely?

I have a Kohler 1.6 gallon two-piece toilet and it is 6 years old. For a long time now, it has been refilling spontaneously, indicating that there is a slow leak between the tank and the bowl. We tried cleaning the flapper and the flush valve. This just made it harder to flush, but did not stop the leak.
Recently, the refilling was occurring much more frequently. I turned off the water to the toilet and the tank was empty within a couple of hours. I decided that more serious tactics were required. Over the course of a weekend, I have replaced the various parts involved in draining the tank. I have succeeded in slowing the leak, but it hasn't stopped entirely. Over a 12 hour period, the water level in the tank drops by about 2"
What should I try next? The only thing left to replace is the fill valve. I can't imagine how this would cause water to leave the tank without creating a puddle on the floor.
Should I be satisfied with my repair? In other words, do all toilets leak a little and I should stop fussing over a 2" drop in 12 hours? In practice, this shouldn't be a noticeable problem, because we'll flushing the toilet so often that there won't be any spontaneous refilling.
