Pilot 78G B Burps And Writes Too Wet.

March 1, 2015

I received it about 2 months ago and for a while it seemed fine out of the box. The last couple of days however it leaves a nice drop on the paper as soon as I take the cap odd and start to write. I dried it of with a napkin and it was fine for a minute and then started to flow heavily. It's always been inked with Daimine Majestic blue.

I have read that squeezing the shoulders together can get it to write drier but can it be the ink? Is Diamine a wet ink? It never was a problem before. The room temperature is steady between 62-68˚.

thanks,

Are you using a cartridge or converter? Try a different cartridge or converter. There might be a tiny air leak.

Converter.

Hmm, I experienced the same issue using Noodler's black with a fine nib in a Pilot 78g, I assumed the problem was the ink and the rather warm and humid weather, because I experienced the same issue on an Lamy Safari xf, and a Hero 329 xf, never thought it could be the pen. The Hero is a bladder pen, the Safari and 78g both used converters.

I have the same burping problem with a Parker 75 (circa 1969) and purchased a newer 75 to test out the nibs I was using. That pen continued to burp but the new pen didn't. Therefore, I'm pretty sure that the feed is the problem: over time the feed pin that fits the cartridge or the converter has either slightly narrowed (erosion?) or Parker changed some dimension material or process). Because the feeds are interchangeable, I'm going to switch them next, rather than just the nibs.

In fact, there's another dimension I hadn't considered: the diameter of the grip receiver for the cartridge/converter. The old grip seems to hold them more loosely than the new pen. I may experiment with finding a firmer way to seat the catridge.

Different problems. The pilot steel nib pens have a known problem wherein if you don't firmly push the nib/feed into the section, they burp.
