I have rarely been disappointed by sleeping on a problem and focusing on the unintended consequences of my actions. A couple of months ago I decided to eliminate the play at the top of the clutch travel by threading out the linkage on the piston rod. Although I did not see the piston depress, apparantly a miniscule movement blocks the channel to the resevoir. As soon as I disconnected the linkage it started to gravity bleed. If I had not used the wrong line, I would not have found this out and effectively would have run with no resevoir-not good I'm sure. Strange how things work out
Thanks again for your help.
