After helping me figure out that I had a bum bowl a couple of weeks ago (leaked out the whole in the back just below the tank), Im back w/ a new problem. The new American Standard Cadet I have won't clear the bowl when flushing. I've messed with the chain slack, the float position, length time holding the handle, and the water valve openning. Nothing will get it to give me a good clean flush. Ideas? Many thanks.
