Before you replace the flush valve, one other thought is to look at this thread -- sound familiar? Then look at Redwood's suggestion at the end and see if that helps. https://terrylove.com/forums/showthread.php?24473-Help-with-flush-valve-replacement
Also, I would call Korky at 1-800-LAVELLE and see if the 4030PK Universal 2" Flush Valve kit (4030BP at Lowes) wouldn't fit just fine. I have installed it on several American Standard toilets that had a different setup than the Korky and it works great. It is, of course, always a bit of a pain to remove and reinstall the tank, so I would try really cleaning the area around your flush valve and make sure that you can't get it to work with the new seal that you bought. Interesting to see, isn't it, that the Mansfield tower thingy is "notorious" for having the seal disintegrate when you go to replace it?
