master cylinder???

[kenwheeler]

I've been trying to get the air out of the clutch line for two weekends. I tried gravity, raising the reservoir, raising the front end and using a bleeder hooked up to my air compressor. I tried pumping the pedal, holding the pedal and having others pump and hold while I bled. I still can't get the clutch to work. Now I have absolutly no clutch pedal at all.

I can't figure out where the air is coming in from. Could it be my master cylinder?
