I received an ASA Genuis fountain pen. I filled the pen with ink and dipped the nib to assist in initiating ink flow. Pen worked great until the dipped ink ran out. I realized no ink was flowing from the barrel through the section to the nib. I soaked the section in a little soapy water and flushed it well. Still no change. Last night I laid the pen on my desk at a slight angel with the nib downward. When I awoke this morning I tried the pen and dry as a bone. My next step is to remove the nib and feed. Question is I do not know whether the stock factory nib is a friction fit or screw in nib? I am assuming it is friction fit but like to verify that before attempting to disengage it from the section. Any advice would be greatly appreciated. Thanks.
