Paasche EZ-STARTER Single Action Airbrush Kit (Great for Beginners)

Cannot get Paasche EZ-STARTER airbrush to work at all. Air blows through airbrush assembly as expected, no paint (or even straight water) is siphoned out of the bottle at all. Using Pro-Line RC Body Airbrush Paint (water-based acrylic). Using air compressor system (not air canister) that I used successfully to spray Bob Dively Liquid Mask using an HPLV air spray gun, among other uses. Tried thinning it incrementally all the way to only 10% paint/90% distilled water, cleaned out airbrush after every trial. Tried blowing straight water. Tried pressure from 20 psi - 50 psi for each thinning increment. Tried taking airbrush apart and cleaning out residual manufacturing oils. Tried adjusting the fluid tip CW and CCW. Air breather hole on the bottle cap is free and clear (not plugged up). Nuthin' Maybe it only works with their pressurized canisters???
