Background info: I replaced my stock clutch, cable, and quadrant last winter. Everything worked great, but I put better headers on and (I think) scorched my clutch sheathing, making the pedal feel sticky sometimes. Late Model sent me a new clutch cable, so while changing my oil I changed it. I set the length just like the first one, with the adjusting nut just getting tight on the clutch fork. When I went to drive the car, I had to have the clutch all the way to the floor to shift, and the firewall adjuster couldn't move the engagement point up enough for my liking. Jacked up the car again, tightened up the adjusting nut several turns. Was feeling confident it would work great, but the car won't go into gear with the engine on. If I try to start the car in gear the car moves. With the engine off the tranny glides through the gears without the clutch being pressed much smoother than it usually does. Also noticed when I was right under the clutch and had someone press the pedal there was a squeak even with the engine off. What could this be a sign of?
