New clutch setup won't disengage

Finally got a chance to look at my setup.

Good news - the disc is definitely not stuck to the flywheel :) With the clutch pedal depressed and the car in 4th, brakes set, it cranks just as rapidly as if in neutral. Trial with the clutch engaged - big bump against the brakes, as expected. So that's good news. Whatever I have to fix isn't inside the Lakewood!

Now "feeling" the clutch pedal carefully. It seems that about two inches of pedal movement occurs before I can really feel the diaphragm spring taking up the load (like air in the system is compressing). There's so little throwout bearing clearance to the fingers that I would not expect that much pedal free play.

Next step is to measure the actual fork movement, as I noted. But I'm sure that the clutch is (partially) disengaging since the starter cranks normally with the pedal depressed in gear. Just not getting enough travel.

For the rest of this afternoon, though, I'm installing my inner valve springs, and a new set of Accel ceramic-boot plug wires since #4 and #6 keep pushing themselves off the plugs due to the heat between the header pipes.
