Clutch issues again!
I've never run a hydraulic throw-out bearing, so I don't have the experience needed to advise, but I will say the .150" gap seems a bit large. Seems to me I was told to set up my manual throw-out bearing to have a .060 - .090" gap when pedal is up. Have you tried reducing that gap?
The other thing that concerns me is you saying the diaphragm fingers being flat when the pressure plate is tightened down. I don't have a lot of experience with 4 speeds, but if memory serves, every pressure plate I have seen tightened down still had the fingers pointing slightly outward so there is room for them to move before they reach end of travel.
I wish I had a picture of mine from a different angle, but I swear the fingers on my McLeod pressure plate were still pointing outward once it was tightened down. The only pics I have at the moment is looking straight at it (see attached)
