Ink Flow Issues In Zebra R301 With Diamine Oxblood

[Edgemcmuffins]

Hello mein inky friends. Today I have quite the conundrum. I recently received some diamine oxblood, alongside a cross aventura and zebra r301. The ink flows fine in the cross and my old pilot parallel, but my zebra r301, which is supposed to be a broad .8 mm, is putting out a dry line of peachish ink at around .5 mm. I had previously used noodler's bulletproof black without any problems, but I soon found that I did not clean out the r301 well enough and it began writing black. It eventually kept lightening until it became the sickening earthen colour it is now. I thought this was do to leftover water and thought nothing of it, but now the pen writes terribly. I believe it may have been clogged somehow. If so, are there any ways to fix it? Feel free to move this thread if I am in the incorrect section; I did not know which board to post this in, but thought you guys would have the most experience.

You could try the usual trick of adding some dishwashing soap / Photoflo with a pin in to the Oxblood. That would reduce surface tension making the ink wetter and more flowing.

Agree with trying the pin drop of sink dishwashing soap. I'd add to a sample vial of ink or converter but not to an entire bottle of ink.

Thank you for your help. I added a tiny pinprick of soap to my cartridge (Zebra doesn't make converters) and now the flows as the lovely blood red I know and love.
