"Feed Flow Rate" Issue

[mtcn77]

Hi, I have a Kaweco eyedropper Classic Sport and Faber Castell pens. Today's question is about troubleshooting the Kaweco's feed ink replenishment speed.

 

The pen writes good after a whole section cleaning. It writes even better when it is cleaned without disassembling the section, but using the miniconverter to flush with 1:100 diluted dish detergent + bicarbonate cleaning fluid until clear of ink.

I don't want to mix dish detergent into the ink that I'm using. I find that to be error prone in case I mess up the dilution ratio and the pen starts burping constantly. However, as it is, after the feed is still wet with the minute remaining dish detergent in the section, the pen has enough flow for a glassy smooth & ample flowing session. The writing experience is very enjoyable.

 

Still, as the supply gets replaced with new ink which is Parker Quink Black - very reliable ink - it does not fill the feed as fast as I write with it. When starting, the feed's gaps are full of ink to the point that if I don't immediately start to write, it will drip onto the paper. It keeps up this wetness for a while without any burping; however loses pace as the diluted dawn detergent + bicarbonate residues wash off.

 

I would like to avoid much testing while still keeping ink flow at that speed which the pen can race with me.

 

PS: I hatched a makeshift solution. I kept the mild detergent solution from the cleaning procedure. I will add more solvent each time I refill the pen. The first time I added it, I used 0.02ml of this mixture. It ghosted and shaded until it gave up once again... I can sense when it will occur from the pen starting to grab the paper, though.
