There isnt one, its a cable operated clutch. Remove the end of the cable from the clutch (under the distributor cap and the air filter housing). Get someone to press the pedal and then pull the cable back through. If it is really tight, renew the clutch cable, £25 from PARTCO. If the cable is free check whether it is the pedal assembly itself. If this is okay, the Clutch is at fault. About £300 to have a new one fitted.
