Suddenly my clutch would not engage when cold / started up for the first time after sitting for at least a day. After idling for a minute or two it starts working. I thought at first there was gook in my slave cylinder because the pedal goes light when coming back up until it starts working. So I took it apart and it was clean. New fluid and back together it does the same thing. If I had to guess I would say it is the throw out bearing sticking on the input shaft tube that it slides on. Before I tear into it has anyone had this problem before?
