 Is this a recent occurrence or has it always been like this?  In other words 
did somebody do something to cause this or did it crop up on its own?

Possible causes are torn diaghram (you checked that), improper 
piston/diaghram assembly (causing the piston orientation to be wrong), low float level in 
the float chamber, vacuum leak (check the brake booster, too), sticking piston 
(it should drop all the way down under its own weight).

Let us know if any of these work.
