When I start spraying with the 150 airbrush the spray comes out OK. About 1/3 of the way through the 2 oz bottle the spray starts to slow down and typically it stops spraying the color at about 1/2 of the bottle.

The pickup tube is set about 3/32" from the bottom of the jar (and I have replaced the pickup tube in case there was a leak). I have tried various air pressures (in 5 lb increments) fro 30 lbs up to 60lbs. There is no difference.
I have completely disassembled the 150 airbrush and cleaned everything including soaking the airbrush overnight.
I have also tried various needle settings.

The paint sprays fine in my Badger 350 airbrush at 35 - 60 lbs pressure so I feel the paint is thinned properly.

I like the balance and control the 150 gives me.

Any ideas/suggestions?
