I have tried to get tech help with this and can’t get this gun to work. It has the .5 tip. When spraying it either doesn’t spray or when it does spray it dribbles paint. I have thinned the paint turned the pressure up down and just about any combination I can think of and the same problem. I have tried running the gun with between 20 up to 60 psi at the gun and same problem. I have thinned the paint and same problem. I am at a loss and have never had this problem with much cheaper guns in the past. Is it possible that the needle and cap don’t match?
