Hi, I got a weird problem with my aztek airbrush, hoping someone here knows...
Basically, i's not spraying any paint. I tried spraying water, but that doesn't go either. When I remove the nozzle, and spray, the water comes out just fine, so the airbrush body seems to be fine. So then I bought a new nozzle, but that still didn't wanna spray anything. Any suggestions?
Try seeing if the needle plunger moves in the nozzle. You can do this just by holding the nozzle, and pushing the plunger into the body. See if it moves, and or sticks in any position. If it does, than there ya go. Tho it's rare, new nozzles can stick right from the get go.
Also try cleaning out the body of the unit itself, Testors has a handy tool just for this pourpose. Mine kept randomly not spraying, and this was the problem. (same with spraying off to one side, again, thought it was the nozzle, when it was a paint buildup in the body itself) Took me a while to figure this one out.
You *could* be cranking the nozzle (s) on too tight, but this is unlikely. (though my first AB of this type had a real problem with screwing nozzles on too tight)
Let us know how it goes :)

Maybe it's the air pressure (either too high or too low) try spraying at 10-15 psi. Otherwise if even with a new nozzle it doesn't work, there could be dryed paint inside the body (where the back of the nozzle connects to the air/paint lines). Try cleaning either with that strange plastic tool they give with the airbrush or with an old brush and a "hot" thinner (such as Testors airbrush thinner: it will dissolve both enamel and acrylic paint).
Hope this helps.
Btw, a strange thing happened to me just yesterday: the nozzle/body wasn't clean enough and, as I pressed the trigger, the air came back from the nozzle to the paint cup: paint everywhere.... :)
