I recently purchased a Kaweco sport classic and have been using it with an included pack of cartridges (Kaweco Caramel brown) for the last week and a half with no issue. After finishing the last of the cartridges I inked the pen up with Diamine Asa Blue using the Kaweco piston converter but I found that the pen would get progressively drier as I wrote and would stop writing after a few pages, needing to have the feed re-primed to get back to writing. I tried flushing the pen and switching to Parker Quink but the problem only got worse so I decided to ditch the converter and refill a cartridge with Quick and have been writing with it all day without any issue so far. I'm wondering if the converter is the issue and how I can fix it?
In case its relevant, the pen arrived with a bad case of baby's bottom but I was able to fix that with some micromesh and it is now one of my favorite writers.
Edit: Forgot to mention that the feed slit isn't perfectly aligned with the nib slit. I tried to remove the nib and feed to fix that, but it won't budge.
