[FC] Unsolvable Clutch Problem in my FC

[Charles]

Charles -

I'm not a wrench by any means but it sounds to me like your clutch cable 
is stretching. Is it new or used? If it is new I would say it just has 
to be "seasoned" if it is old I would suggest that maybe a few strands 
are broken inside the cable where you can't see it. The only other thing 
I can think of is the cable mounting ends are not secured solidly, even 
a little bit of slack can make a difference.

good luck,

Charles
