If the clutch work won't work with a single pedal push, but will after pumping it up to build pressure, then it's a hydraulic issue and adjusting linkages, cables, pivots etc. will have no effect. It sounds to me like you've got some air in your MC. You can continue to bleed the system as normal and hope to purge the air eventually, or you can remove the MC and bench bleed it. Do a search for more info on that technique. A third alternative is reverse bleeding, where you force clean fluid up through the bleeder and into the MC, which is based around the idea that it's easier to make a bubble go up than down. You'll need a large syringe or pump or turkey baster or something to move the fluid up, and make sure you don't overflow the MC as that would be bad, mmmkay?
