Make sure the brake fluid tank is completely full
Also, start with clutch fully up, pump the bleeder tank to 22psi. get under car and open bleeder.
When air noise stops and a steady stream suddenly appears, tighten valve.
Get in car and try clutch pedal (fill the brake fluid tank first as it will have lowered)
Might be perfect right there.
If not, repeat
