I have a nice Jr Gent 1 fountain pen that seems to have a problem with ink flow. I get it writing and it works fine until I stop writing and put it away for awhile - sometimes less than half an hour - then it won't write and I have to fuss with it to get it going. When writing it is smooth as silk (for a cheap nib it writes really nice. The ink has been in it awhile. I have cleaned it with warm water until everything flows clear still the same. I'm not sure what Ink I have in it probably the stock that came with it.
Probably will clean it and change the cartridge again but is that likely to fix it.
