I cleaned it out and when I put it back together it start back flushing paint for some reason.
Its the same one as the airbrush in the youtube video clip you sent me in the link, I us wicked paint but the thing about it is it will not even spray water, when you press down the trigger the water jumps out of the cup.
when I take out the needle it still dose the same thing, the only way Iv stop it from happening is to take off the air cap body.
I can't post a link yet, but if you Google Don's airbrush tips and go to the Master G22 review page, down at the bottom under Postscript are a couple of pictures and text that might explain what you are seeing. If the nozzle is recessed just a tiny bit, air will blow back into the cup. This can happen if you over tighten the nozzle and crush the rubber o-ring.
I think I need 4 posts to add a signature, so I have a couple to go.
Oh Hey! this one counts!
