Yup correct :), you don't want to go too far and preload the system. That could be a possibility in this case too.

The 1g's can suffer from the same thing too with new parts and a good pedal asssembly. I can get my 1g to preload as well if I adjust the rod all the way out. I always adjust every clutch I work on to the highest point possible without preloading it.

You can easily check to see if it is preloaded by going over to the slave and pressing the piston in by hand. It should slide in easily without the clutch pressed down. If it is solid stiff and the piston won't move, it is preloaded. Using this method I can get the engagement point pretty high. Good for your tranny, synchros, and shifting over 8k rpm
