No 1, these clutches arent adjustable.
No 2, as Mr Jenko stated check the master / slave on the clutch, they are famous on these to go out. if you have no clutch it will scrub loudly when engine is running, but will shift between gears when engine is off. my .02 is change both master and slave and bleed it clean.
No 3, no 2 can be intermittent one pedal stroke will be fine the next nothing. just fyi
