I have a 400NN and it seems like there is too much ink in the feed. I recently cleaned out the pen and changed inks (from F-C Brown to DA Whisky). When I went to write with the pen droplets of ink would randomly fall out of the feed and onto the page. I thought perhaps the ink was too thin and flowed too easily. I have since switched it over while evaluating mystery ink #12. It's not as bad as the Whisky, but I noticed what seems to be excessive ink hanging in the feed and on a couple occasions I had drips on the page. I don't remember the F-C ink having this behavior.
I've cleaned the pen multiple times, so I don't think there is any debris. I've soaked the nib unit to clear out any residual ink. There isn't any ink getting past the piston seal into the piston threads / mechanism, so I don't think it's letting air get through the other way. I've tried reinstalling the nib unit clean and dry. I've also tried it with a tiny touch of grease on the threads. Nothing seems to change the amount of ink hanging in the feed.
Is this normal for the older feeds and I've simply never paid attention to it? Did I somehow break something when I cleaned it out?
