Unhook the master from the assembly and see if you can move it then.
Whats the history on this? Sitting for a decade? Fine yesterday and not today?

Sorry the video was too hard on my eyes to make much use of it. I could tell that it barely moves though before it seemingly hits a wall. I could not tell if the master was connected or not.
 
everything was connected.. i have a build journal of the car.. it did not do that on the first 10 starting attempts ( last year) broke my fuel rail it sat just over a full year.. was inside the car today puting stuff back together and noticed this problem... but yes you hit the nail on the head... clutch pedal moves about a quarter inch before getting jammed up... will unhook master tomorrow and give it a try
 
Crack open the slave cylinder and push the pedal down once and then tighten it up again maybe there's an airlines order food is unable to move because its jammed up
 
IMO, if its been sitting that long, your better off replacing the master, slave and fluid anyway. Its wont be very expensive at all and you'll have peace of mind for future use.
 
My guess is pump up from a misadjusted pedal. Try following the procedures here if you haven't already:

If you have and it the proper adjustment didn't work for you, I'm at a loss and other than inspection would suggest replacing parts.
 
You also have to remember that brake fluid is extremely hydroscopic and absorbs moisture. I wouldn't be shocked if you have heavily contaminated brake fluid. Start first by bleeding out all the old fluid and cycling through new fluid. You may need to replace a master or a seized slave but I would at least try this first.
 
Would water in the clutch fluid have any impact considering the operating temp range isn't above the boiling point of water?

I would agree he may have accrued air in the clutch system perhaps which might have impact, but not impact from water. Of course you know infinitely more about clutch systems :)

The biggest issue with brake fluid contamination from moisture is corrosion and damage to the master and slave cylinder bores and pistons, resulting in damage to the piston seals and causing spongy pedal if functioning still, or seizing the piston in the bore causing problems.

If he popped open the slave cylinder bleeder and the clutch pedal pressed down no problem then cool, flush the system a couple times.

More than likely though, he will need to replace his slave cylinder, flush the lines and disassemble his clutch master cylinder and inspect/rebuild it with the OEM rebuild kit.

A brake system is common to see more contamination issues, especially in ABS setups where it can cause damage to significantly more parts including the ABS pressure module.

With a clutch system, you normally would see more air/sponginess issues as you decrease the compression volume of the brake fluid. Normally you don't see it causing a seized pedal unless the master or slave are damaged or internally corroded.
