An update to those who may be interested in how this turned out. I am using Dot 3 for fluid. After not being able to get to my jeep for a couple of days. I decided to first use the test to crack the line at the master cylinder to see if the vacuum if indeed that was the problem would release the piston allowing it to travel normally. Well I did not need to go further. The piston is even slower today than it was when I first posted my problem.
So I removed it and benched tested it without fluid and the line ports open and the problem still occurred. So the problem is still in the master cylinder. I could try and bore it out a little more but I am afraid it will start leaking. After toiling with this beast for about a week I think it is time to move on and get me another.
Thanks for all the advice. Even though I could not resolve this it was indeed a learning experience I don't want to repeat.
