I recently acquired a lever-fill Esterbrook desk set with the 8 ball receptacle. The sac (ossified) and j-bar (rusted and broken) were shot and I replaced both, using a 54mm j-bar purchased new.
It all works OK, except the lever wants to sag open. Previously I was advised this was due to lack of tension in the j-bar, but this one is new and appears to fit flush against the barrel.
Any other suggestions to make the closed lever stay flush with the barrel?
Question 2: Is there a rule/guideline/suggestion on seating replacement j-bars? Do you slide them in until they stop with reasonable force, far enough to clear the section nipple plus "a bit more"?
