Thank you for your help. I've checked the nozzle-needle coupling and they match according to this image (the official Harder&Steenbeck site is a bit confusing): I've then checked the needle position and the tightening, trying to tighten a little bit more than before. I've noticed a small improvement so probably something was a bit loose and I've tried to spray paying attention to not releasing the trigger before having pulled it forward. That seemed to remove most of the sputtering, with Vallejo Model Air slightly thinned. I then tried to spray some black primer (Vallejo): probably not the smartest thing to do with a .2 nozzle, but the results was a disaster. I wasn't even able to spray once. The airbrush clogged instantly and then released a giant splotch. Paint went literally everywhere, inside and outside of the airbrush. I found lot of paint on the needle, the needle cap, in the air cap, on the treads of the air cap and some traces even on the trigger and on the back of the needle seal... It took me a long time to clean everything (at this point, I've spent far more time cleaning than painting). Is this a sign of something wrong or was I just dumb in trying to spray primer? Thank you again Michele

Hi, I've recently purchased a Harder&Steenbeck Ultra 2 in 1, to replace a cheap chinese airbrush that I've been using for the last six months. Since the first test with the new airbrush, I've had the same problem: it sputters badly as soon as I press the trigger for air. It starts sputtering few seconds after loading the paint, projecting a small cloud of darker dots or a larger, single drop farther away. I've thought that the issue may be the thinner ratio, so I've tried thinning the paint I'm using (Vallejo Model Air) much more than usual, adding flow improver, changing the pressure. Always the same results. And the sputter presented also with Tamiya paints (diluted 1:1) and with the 0.4 needle included in the box. I've spent a lot of time cleaning thoroughly every part (I've noticed that there seems to be a lot of paint accumulating in the needle and and the nozzle), checking for cracks or bent needle, but nothing seems to be out of place. I am a bit disappointed because I've never had this kind of issues with the chinese airbrush... Am I doing something wrong or there's some problem in the airbrush? Thank you Bye
