Dean:
I've experienced an identical problem with my '73 1500. After doing all the
same bleeding exercises you did I finally replaced the clutch m/c with a new
one. I also replaced the clutch pipe with a new one. The car has been
great until just a couple of days ago. Same symptoms arising.
I suspect that the slave cylinder needs to be rebuilt or replaced. It may
be that the bleeder screw is sucking air or that the seals are faulty.
Anyway, that's my plan. If anyone has any other thoughts I'd appreciate it
and I know that Dean will too.
