Hi all,  I'm rebuilding an Ampico top loader upright for myself.
It was very much untouched before I got to it (what fun!) and I have
now a tubing question.  On the spring pneumatic, there's a very small
pneumatic which counteracts it; what does that get connected to?

(I've seen compensating pneumatics on the stack before on late model
A's.  Mine doesn't have that, but only on the spring pneumatic).
