I have two single action hobby brushes ... the type with glass jar underneath that paint is 'sucked up' tube. I just cannot get either to draw paint anymore. Tubes / nozzles are all clean and clear.

I've diluted down so far that its not 'milk' as they advise - but like water ... then it blobs !! 

Waiting for a new Dual Action brush to arrive ....hope that will be better.

My compressor is the standard Badger /Debliss Airbrush compressor.

I have a dual action Pasche and that will happen also some times,I use the small cup and keep filling it or try putting less paint in your jar.

I have the Pasche also, there is a tiny washer/seal  inside that will leak vacuum by the shaft and I replaced mine and then it worked great again.

I've got a harder and steenbeck ultra, never had any issues with it at all, as long as you clean it properly after use.

Well I always stayed away from Dual Action brushes ... having had a Humbrol Hobby Airbrush many years ago and converted fridge compressor. Worked a treat. But finally I thought ... the Tramex and other single action I have are not working with my DeBliss compressor.... so I bought a cheap Chinese Dual Action .... when I say cheap ... I MEAN CHEAP !!

Once I had connected up a hose ... not supplied but they give you a screw on adaptor ... works an absolute treat !!  It even worked with my poster paint at more than milky yoghurt consistency !

Roll on next camo model !!

I've used a couple different pasche  and now am using a badger 2 stage. Needles and seats do wear down and rut out pockets. Acrylic paint is water soluable but it is also very abrasive.

I would first replace the needle/seat. Verify your air lines are clear and I think you'll see it start to siphon and spray again.
Fly like your mad at it.

The single action air brushes were actually never used ... they sat in their boxes waiting for me to get them out. I have the dual action brush now which works a treat ...
