I found a Shop here in town and I took my injectors to him.
He reached under the pulled out a little tool screwed it into the end of the injector and "plucked" the seal and screen right out of the end of the injector.
What he pulled out was a rusted/remains of a screen and a bunch of rust!
Then he pick up another and it looked just as bad!
This tool looked like the one I have in my tool box for Schrader valve maintainence, or he had a special "dry wall screw tool"

Called two days later and I picked them up and he said they all flowed at 79 something and I was on my way.
So I went home and cleaned the fuel rails, and it was full of rust and junk like the bottom of a dirty fuel bowl!

If you have a engine that has been sitting for a "unknown" amount time, things happen with the fuel system, so I would put this step in the budget BEFORE trying to start the engine!
