Hello all. I have a beautiful Danitrio Raw Ebonite Densho pen that I got from Kevin (aka Winedoc). I seem to be having flow issues with this pen. I filled it with Waterman South Seas Blues, and when it writes, it is great and smooth. However, I can only seem to get 3 or 4 lines written before the flow stops

, even with the end cap opened to 3/32". If I open the endcap further and invert the pen 2 or 3 times, the flow returns, but only for another 3 or 4 lines. When I filled the pen, I let it sit on a gentle downward slope for several hours (ala The Noble Savage). I even soaked the nib in the ink like Tytyvyllus and Bryan have done, with no improvement. Any other things I can try? I want to get this nailed down before I ink a Raw Ebonite for my wife or my Tamenuri Urushi. Thanks a lot.
