Front brakes won't bleed, even with vac!

[imagesinthewind]

So, you may remember that I needed a new master cylinder back in Sept or so.

I had some trouble getting the front brakes to bleed. Took everything off and tried again. The back bled easy. The front still nothing. I bought and tried a mightyvac and while I can draw some brake fluid out of the left front, when the brake is pressed, no fluid comes out on it;s own. The right front has brake fluid coming out, but not shooting out like the back does.

I had a vac leak, but I used black gasket stuff and that is solved.
So, What the H3LL am I to do now? Even the mighty vac doesn't seem to help. And my hand hurts from trying. Is ther a way to get the vac to blow instead?

I can feel the air sucking and blowing on my finger if I hold it over the screw.
YES there is a full front chamber on the res, I pumped it up with the little pump on the top of the res. If I can feel the air sucking and blowing, see a small bit of fluid blow out of the screw, then there is not a blockage.
I am loath to take it all off again, I'd lose the gasket I made.

What can I do, please help! Thanks to all!
