[DeTomaso] Update.... still no go.... Re: Clutch woes in Asa's garage

I feel like I've wasted a whole day on this.  If I adjust the slave so 
the throw-out bearing is resting on the fingers of the clutch (which I 
don't want to do), then I finally get enough disengagement to barely get 
it into gear, but there is still some resistance, like it's still not 
disengaging fully.

At rest, I can manually move the slave piston back into the housing 
between a half inch and an inch (guess here).  All this seems to do is 
push fluid back into the master reservoir.  The point is though, it 
doesn't move back on it's own.  I have a pretty darn stiff return spring 
on the slave and the master appears to be returning to rest as well.  So 
my overall problem appears to be the slave not compressing enough to 
give me a long enough throw.  I'm not sure a long throw will help out.  
I hate to spend the money on one if it won't solve my problem.

The thing that really bums me is that I thought it used to work just 
fine before I replaced the pressure plate, disc, etc.  But then again... 
it -was- toast.  <sigh>

It's starting to look like I may not get to drive it this year either.
