I have replaced both ball studs, new bushings, and checked for bind. Everything seems to be smooth. I even installed a second clutch return spring. I have the proper throw out bearing adjustment. I have to help the clutch pedel with my foot to return all the way. Does the "Over Center Spring" have an adjustment, because with the linkage off, the over center point of the pedal seems to be almost at the pedals highest point.(ie. near the up stop). Any ideas? Thanks.
