I impulse bought a Pilot Metropolitan (F) about a month ago and have had the worst experience so far. First it took 3 days of experimenting (squeezing the cartridge, flushing, cleaning, shaking, incessant scribbling) to get it to write at all. Then I noticed the nib was a bit off-center in the feed so I aligned it and it wrote pretty well for a while. This morning I grabbed it to take some notes and it won't start, even after a flush with water and re-seating the cartridge. This isn't my first fountain pen (not even my first Pilot!) but I'm really disappointed because the Metro seems to be such a popular recommendation as a solid, inexpensive starter pen. Did I get a dud?
Sounds like a dud. What surprises me was that reseating the nib made the pen work for a while, and then the pen stopped working suddenly.
A few troubleshooting questions: Have you tried a different ink? How about a different cartridge?
put a sheet of paper/napkin/tissue on the top of the slit. Are you getting any ink? Or is it dry? If it's wet, it might be something preventing the ink getting to the tip of the nib In this case, I usually try a different ink or gently adjust the tines in the case the tines are too far apart. If it's dry, I reckon it's more to do with how the nib is sitting on the feed. The best you probably can do is try to reseat the nib/feed.
This one will be messy. With the pen stored nib down with in the cartridge, wait like 20 minutes. Now pop off the nib and dab at the feed with paper/napkin/tissue. Is the feed saturated with ink? If it's saturated, once again it's probably something to do with how the nib is sitting on the feed. Reseat it and hope for the best. If it's dry, I really don't know what to suggest besides binning the pen. A Metro isn't worth enough money to buy a Kakuno just to transfer the feed over.
