Anyway, I do not know if my airbrush is fine, because when I shot back to expel more paint or when I'm cleaning, in the middle, where it is seen that the needle passes, I see that the needle is bent, so I think to return to his position rubs the tip nozzle, the nozzle fact that I had a burr removed with a file and the needle tip was slightly bent. it is normal to double to pull back? your airbrushes do ?. when at home I will record a video. my airbrush is a "ventus titan"
