airbrush hell-p!

Are you pulling out of a paint cup or a bottle? If the latter, check that the air hole through the bottle cap is not plugged, the tube is not partially plugged, or up against the bottom of the bottle. If the former, then maybe your brush needs cleaning and/or you need more air pressure.

More air or thinner paint, using the Ceramcoats, Anita's and other off the shelf acrylics, they need to be pretty well thinned, which can be a real pain in the butt to get right using the small quantities we use, like in the paint cup. Should flow like milk. This is why I normally spend the extra few bucks for Createx and spray it right out of the bottle.
I have the same gun and it will spray those paints fine, maybe not as nice as an Iwata.

don't forget temperature, if it's below 70 it won't spray I have found.

and what those guys said.
