Troubleshooting Jinhao 992

[linkoiram]

Hey all,

Got a pack of jinhao 992 pens last week and I've given a couple to friends, broke one nib through oversmoothing, and the rest have been pretty good. One thing I have noticed, is that one is particularly troublesome. I am using diamine ancient copper in the pen and after some smoothing it writes really well at first, but after a few minutes of writing it skips and gets scratchy. I have checked the tines and I feel those are fine, not sure about how well the feed is aligned but it came without the feed being perfectly aligned, not sure how important that is. I did notice that this one has a converter that wasn't super well sealed to begin with but I pushed it on tight.

 

Need some help troubleshooting it, I'm pretty sure it isn't the tines or any baby's bottom issue I feel like it is due to some drying of the ink quickly, because when I use the brass shim it writes very smooth right away but gets scratcher over time.

first thing first, drain the ink, thoroughly clean the pen parts ( the parts ink goes ) inside out with soapy / detergent / whatever come handy , and cleanse it well with wate and let dry then re ink and see if the issue stuck, just as many , this is usually the first thing we Chinese fountain pen user do , a ritual so to speak to prepare the pen , next, write a full fill or 2 , then stat to judge if the nib / feed / ink flow need adjustment or tuning ... another particular with almost all Chinese fountain pen .. they need run in ( like a new automotive engine )
