The tines may be too tight so my suggestion would be to floss the tines. It should be no problem if you have a brass shim. It’s worked wonders on a number of my cheaper pens to fix ink flow. Although I have noticed that the flow is slower on my 9019 as well.
Remember when we had a whole impeachment hearing against Trump for withholding aid to Ukraine so he could get a political hit piece on Biden? I’m wondering how long it will take before a quid pro quo scenario pops up again. Either in Ukraine or elsewhere. So ya, we’re all feeling for Zelensky in the next few years.
