Hello. Someone gave me a Parker Classic with a medium nib sometime ago. I had some difficulties getting it to work right with an international cartridge with Monteverde ink in several colors, always leaking, didn't write quite right. Switched to Parker Quink ink black, same issues, plus it didn't look black but gray.
Then I got a Parker converter, and was amazed to find that the gray looking Parker Quink ink transformed into a beautiful black ink, almost as dark as Noodler's black, just from adding the Parker converter alone. The leaks greatly diminished also, but did not quite go away. I wondered whether silicone grease applied somewhere on the nib would help, but hesitated to experiment.
Then I read about someone having leak issues with a Parker 180 and the Quink ink, which he claimed they went away when he switched to a drier ink, Sheafer I think (the 180 and the Classic use the same nib, I am told). So I switched to Noodler's blue, the driest ink I currently one, per experience with other pens. All leak issues went away, and it writes a rather wet line at that!
So the question is, do I have a problem or not? While I am glad to have a combination that works, I am not happy that a Parker pen doesn't work with a Parker ink supposedly designed for it.
Any thoughts on this issue appreciated.
P.S. On the leak issue, it made some difference whether I inked the converter from the nib, or with a syringe, and whether the pen was completely dry of all water after a rinse.
In the current non leaking situation, I filled the converter directly, avoiding the nib, and started with a completely dry pen, so I am not entirely sure the leak is fixed since I took steps to avoid it.
