Help with bleeding front brake

[Davepick]

First of all let me say that this is not the first time I have bled the brakes on a bike, so I know how to do it and how it should work. I have tried the traditional tube in a jar approach and I’ve tried the vacuum approach – neither work. Any suggestions as to what may be the problem would be welcomed.
On funny thing, it almost appears as if the bleed screw is the wrong thread – it screws in OK but it feels loose. I can tighten it down but as soon as I back it off a tiny bit to start to bleed, you can move the screw very slightly on the threads – probably enough to let in air – seems like it shouldn’t do that to me – any ideas?

take top off front revs, suck out old fluid, fill to about 1/4 inch from top.
open lower bleeder, slowly, {I SAID SLOWLY] pump lever. add fluid till clean fluid is coming out bleeder, as you pump the lever ,close the bleeder! clean up, check operation ,put on top! go ride!
all bleeder feel that way, its normal!!!!!!!!!!!!!!!!!!!!!!

Check to see if you have dirt or any other junk around the piston. Sul took mine apart and found dirt buildup around the piston causing it not to bleed and stick.
