Stretching Clutch Cable?

[Rosco]

OK, well i have another couple questions. Got my car up on a lift today at work so i could easily get the dust boot off covering the connection of the clutch cable and the clutch fork. (i've got about 2 inches of dead play in the clutch still) I am wondering, how taught should the cable should be between the bellhousing loop and the clutch fork? Also, i'm wondering about the self adjusting mechanism. I'm not sure if the moved the retaining pieces that snap onto the pole. I was reading my shop manual today and it says that when the retainers are snapped back on it should be about an inch away from the end of the poll. Right now its about 1/4 of an inch, if not less, away from the end of the poll.. Also, does the self adjusting unit just pull up slack in the pedal itself, or does it do anything with the quadrant on the right side of the pedal? I was also wondering, about the distance of the retainers and the pole. The further the retainer is from the unit itself, does that give or take slack? Thanks alot
