What indicators point to needing a new needle packing O-ring? My two Iwatas have been sitting for over 20 years, and I've only tried out the HP-C recently. Seems to work okay, (testing with Rotring inks) but I wanted to test it out more thoroughly this weekend.
The air valve assembly was a bit sticky, so I disassembled it for a brief cleaning, and now pressing the trigger downward yields a much smoother movement.
Curious to know what to look for as a sign that the fluid needle O-ring needs replacement.
