is the clutch adjustable on the mazda 323f j-reg 1.6 thnx

Not at the clutch itself, but there is a threaded rod between the pedal and the master cylinder which can be adjusted. You will find it easier to get at if you remove the front seat and the bottom half of the dash.

By the way, if you are having clutch problems, there are a couple of documented cases where the metal tears on the chassis where the pedal bracket top mounting goes so the whole bracket moves and cocks everything up ...

ok thnx mate but i think the clutch is knackered
