Clutches are not adjusted according by the amount of the thread on the linkage. The idea is to get the throwout bearing just off the pressure plate fingers when the clutch pedal is released. Also to make sure that when the pedal is depressed, the engine is disengaged from the transmission..
Chip is right, a general rule is to have about of inch of free pedal travel before the throwout bearing touches the fingers..When the clutch is depressed the pressure plate releases pressure allowing the clutch disk to move back from the flywheel...
WIthout seeing your linkage it is tough to tell what you did wrong.. Do you have a shop manual to check to be sure the linkage and return spring are installed properly ?
