Have you adjusted the clutch pedal?

About 3/4 way down there is how you do it if you dont know. I also had this problem with mine when i put the 6bolt in(with an ACT flywheel and 2600). I also had a new clutch master and slave cylenders. I adjusted and it helped for awhile but then it went back to the way it was. Then I adjusted again and it was fine for awhile again. Another thing that helped was when you put my tranny back in another time we put grease on the TOB and the Falcrum and the slace where it hits the fork. that helped out the most.
