24. Q. If lubricator feeds regularly when working steam and too rapidly
after shutting off, what is the trouble?

A. The opening in the choke plug at the lubricator or through the steam

proper size by applying new chokes or valves.

25. Q. When valves appear dry while using steam and the lubricator is
