[DeTomaso] Asa's clutch

 Asa, the only way the piston could not return into the bore is if the clutch is not returning to its rest position.? The clutch applies a hundred pounds or whatever of pressure and it is not possible the little spring could prevent the piston from being pushed back in.? Does the pedal stay down and just slowly come up?
If that is what is happening then you do have a problem with the backflow from the slave to the master.? 

>From what you are saying, with that strong and long of a spring in the slave you are never going to be able to adjust the linkage properly. I don't know what it is there for at all and I would remove it if I were you.

It seems to me that using a stronger external spring could overcome the internal spring, but to establish the proper rest position you have to have an unloaded / unsprung point, from which you then attach the external spring to pull the arm a bit clockwise to remove any load on the throwout bearing.? 

At least that is my recollection / understanding.? Anyone, is that correct?

Jim

I think that's just one more reason why I should replace this with 
another unit.
