Iwata Eclipse air problems

Hey guys, I'm about to do some research on the tube on a problem I'm having with my airbrush. In a nutshell, if I tighten the hose on the airbrush to where it is finger tight and the connection is not leaking air, it seems to close up the air piston and make it where when you depress the trigger nothing happens. The only way I can get it to work is to loosen it about a quarter turn (the hose fitting) and then it will pass air. But the dang thing leaks like a sieve (sp?). I have a moisture trap that goes on the airbrush between the hose and the airbrush that has a little bleed valve to blow the moisture out of the line. It does it with that as well.

This is throwing a major kink in my build. Do any of you pro painters have any suggestions? I've tried lubing, cleaning, everything. I have not taken that inlet valve apart yet (I'm a wittle scawed!)

Any advice is appreciated.

Might have a little bit of dried paint in the air valve, or a bad air valve. My eclipse started doing that. Took it apart, cleaned it and put a tiny bit of airbrush lube on it and it fixed it. After you lube it, I would definitely spray a cupful or two of thinner through it to make sure there's no more oil in the air path.

Thanks Chris, that was what I was going to try tomorrow.

Got this thing fixed. It was an o-ring that seemed too big for the application. It was presumably to seal the connection between the valve and the hose. I pulled it, used some teflon tape, no licks, no worries. PSI like a mutha!
