Clutch engagement point at the very end of pedal travel
I've had my engine and transmission rebuilt on my '07 Elise, since I wore them out with lots of tracking. As part of the rebuild, my mechanic installed stronger clutch springs, so it takes much more pedal effort to disengage the clutch. He's also bled the clutch twice.
Due to all the changes, my clutch engagement point is very strange. When I need to disengage the clutch, I have to push the pedal all the way to the floorboard, and even then, I think it's partially engaged because I have a little bit of difficulty getting the car out of gear, I have to fight a little bit against the transmission. When I'm in first gear and trying to get moving, the issue is the opposite, I have to let the clutch out almost all the way to the end of pedal travel before it starts engaging, and then it goes from 0% to 100% almost immediately, leading to some jerky driving. Shifting from gear to gear, it's a combination of the two, I have to get it all the way to the floor to disengage, then let it out almost all the way to engage.
I'm at a loss as to what's causing this, because it's inconsistent with air in the system. The master or slave cylinders don't seem to leak, since I can press the clutch in for quite a while and it doesn't seem to re-engage as it would with leaky pistons.
