Over center spring with hydraulic clutch bearing?

Sorry, I missed in #1 that you have a 3-finger pressure plate. Usually when removing the overcenter spring is mentioned, it's a diaphragm clutch. If the overcenter spring helps, leave it in. I have a diaphragm clutch, something in my mechanical linkage (with the overcenter spring in) won't allow my pedal to come back up when pushed in. Everything has been put into alignment, but no go. So without the overcenter spring, my diaphragm is just as hard to push in as your 3-finger. So, have been watching for posts of hydraulic clutch applications, they are supposed to be a little easier than what I have now.
