some clutches can bleed themselves by gravity just by opening the bleed screw,keep the reservoir topped up and try getting someone to press pedal and open the bleed screw,shut off and get the pedal pressed again and so on and you might get a good pedal that way,the other way is to get a pressure bleeder which works on compressed air but if you don`t have access to this would try the first options,good luck
