Airbrush Ink

no paint coming out of Airbrush?
for christmas i got a bottom-feed Airbrush, paint, and a compressor. using the open-bottle “siphon” thing.
i hooked it up to the compressor and tried using it. the air came out perfectly and looked like it was fine. because of this i assume that the needle is clear and there is nothing blocking it. but when I put the siphon-bottle-thing up to it and put water in it, the water just bubbled everywhere. I tried it with ink and the exact same thing happened. it just bubbles everywhere.
any suggestions?
Might be the air to paint ratio isn’t right – there should be an adjustment screw so you can fine tune it. Also is paint to thick – should be the consistency of heavy cream. Make sure paint has no lumps – can strain through a piece of old panty hose. If it will go through the panty hose it will go through the Air Brush. I always found that around 25 psi worked well with my Air Brush. Always be sure to rise and keep needle valve clean and you should have lots of fun. I love to Airbrush!
