No corrections, but just for balance: I have successfully re-centered the
shuttle a number of times using the bleeding method Barry described. The
first time I had to crack open both circuits a couple of times because it
is difficult to tell which side the shuttle has moved to, and because it
is easy to overshoot. The second time I only had to open one side -
guessed right and didn't overshoot.
Cheers,
