Default clutch bleeding problem. (surprise) :/

I have a US brake 7/8 master, ran through -4 line to a 98 OEM GM slave cylinder. Bled the master, bled the slave with **** poor results and NO clutch movement. I bought a mity Vac, pulled air out, still no clutch engaugement. I had my dad push the pedal as i opened the bleeder, had him hold it down, till i tightened the bleeder, he would release, and then id crack it as he'd push, and so on for 15 times. The fluid coming out was clean/clear with no bubbles, but it seemed like only 25% of the pedal's movement was actually pushing fluid through, at a VERY weak flow. usually when i bleed a clutch slave and i just crack the bleeder and push the pedal it squirts HARD and you feel it in the pedal. Thats NOT what i am experiencing at all. im out of ideas and im VERY pisssy about it. Anyone have any ideas? thanks

This has to be an adjustable master? Have you tried to adjust it up to get it to push more fluid?

I would have to say defective master. that thing should be way overkill for a LSx slave. The stock masters are 3/4" bore approx.
The McLeods are 13/16ths". 7/8's bore should push that volume really easily.
