Ok folks, I need some help. I was very happy when I received my PS-270. However, workload prevented me from testing it until today. All I did was ran some water through and then sprayed fountain pen ink. I noticed that airbrush was working more like a single action brush, that is, the airbrush sprayed ink as soon as the trigger was depressed. There were no bubbles in the cup though. I know this problem happens when the needle is not seated well in the nozzle or if the nozzle is not clean enough. Well, it is a brand new airbrush and I had no reason to believe that nozzle or needle was dirty. At any rate, I took out the needle and wipe cleaned it with isopropanol and after putting everything back together, I sprayed 2-3 ml IPA through the airbrush. Then I tried to spray the ink again and same problem occurred, in fact this time the lines were wider. Using my 10x loupe I inspected the nozzle but couldn’t identify any cracks or something. What should I do? I already wrote to Chad of spraygunner.con and hopefully he will find a way to sort this out. In the mean time can somebody tell me if anything can be done to address the problem? Thanks.
