Not enough air



I'm having a issue with two of my airbrushes... for some reason I can barely get any air through them... even with the compressor cranked up to 60psi. I have completely cleaned them and even replaced the needles and tips... I am at a bit of a loss as to what the problem might be.

I use (reduced) Createx Wicked acrylics through them. One of the airbrushes is my prized Harder & Steenbeck 2 in 1.
Could it be that, somehow, paint has got into the air channel of the airbrushes?..
Any help or advice would be great... Thanks
Could be, that valve can sometimes get stuck in place so also needs a good clean, also have you checked your lines without brushes even on them, just to make sure they are all fine.....blockages or splits etc
have you tried any other AB with the exact same lines and quick releases (disconnects) ?
did you use the same paint in these two the last time you worked?
Agree with fezzly, I believe that's what it is.
