last one i drove with new clutch bit 3/4 travel , they have self adjusting back plate that as clutch wears it rotates and takes up any free travel,, its possible a simple bleed or have found on some can give this mech a shock and maybe get it to rotate by stalling the car in reverse on a hill a few times can shock this adjuster back to giving the correct bite point failing that might be rusted up or jammed maybe,, link below shows how it works,
