My questions are what style of clutch do you have? Diaphragm or Borg-Warner and is it a normal model or H.P. unit? Huge difference in the effort it takes to operate a Borg-Warner style unit compared to a diaphragm type - I mean just that simple difference can mean a car that a 85 pound woman could drive (with diaphragm) versus one that she couldn't push the pedal in on. If it's a race unit compared to a street unit, you can about double the effort required.
