I'm going to rebuild the slave too just because, although the more I replace the more my new parts can catch me out too.  One more local race before the 4 day tow to the Cup in Portland, would much prefer not to break it again there.

>> Sudden change in clutch engagement point on clutch pedal and slipping clutch when pedal is up.  Engagement point moved from near the floor to near the top of pedal travel.  Happened suddenly.  Clutch fluid is at normal level.  Clutch will still engage, but not completely - like I'm not fully releasing the pedal.

>> Guesses?  I'm suspecting something with the clutch fork (maybe a pin came out and jammed in the throwout)?  Slight chance of hang up in slave cylinder, but those are so simple it seems unlikely. Of course I'll report back when I know the actual cause.
