What a lot of work! I've only been using fountain pens exclusively for a couple months, but the adjustment back to a BP was just uncomfortable and unpleasant. Dragging the point across the page to lay down that gummy ink was hard slogging. After one page of notes, I had had enough. I went to the bathroom, washed off the ink as best I could, grabbed several squares of TP to act as an emergency blotter, and went back to the Wality, leaks and all.
Thoughts on 1) how to slow the flow of ink or 2) diagnostics to address the leak? I'm thinking the answer to 1) may be to gently adjust the nib, but 2) seems to have to do with how the feed is seated, which seems tricky.
Ultimately, it's only a $20 pen -- I'm reluctant to pay to have it serviced, so I think I'm looking at my first attempt at FP adjustment. However, since it's an eyedropper filler, I think there are only five parts to it, including the cap, so how complicated could it be? Yeah, complicated enough for me to ruin it, but that'll be almost as much fun as fixing it.
