Stinger Airless Sprayer dead?

I picked up a Stinger airless sprayer at a garage sale. The motor was fine. I’ve managed to clean all the gunk out of the lines and gun. I’ve tested it with water. Water pumps through. I’ve tested it with latex paint. The paint pumped through but does not atomize at the gun. The paint squirts out in two solid streams creating a blob of paint on my cardboard work area. Am I missing a piece on the gun that helps disperse the paint?
