Thank you guys. I got it fixed some time ago by doing a VERY VERY VERY good cleaning of the gun. I always clean the ABs good, but the nozzle can be tricky if you have something stuck there (which I had). The createx I use is a bit old (bought the bottles from a friend who never got around to use them) so they need that extra hard shake and some of them need to be diluted and strained.
And no, nothing wrong with the Revolution. I have three ABs now, the revolution cr, a hp-bc and a grex xn and I think I use the revolution most still because the ease of use when you want to just use couple drops of paint and don't have to worry THAT much about the consistancy of the paint. Of course, the hp-bc and grex xn both feel much better, the trigger is so smooth and all, but for the hp-bc you need more than the drops of paint and for the grex I have to be very careful what I put in it or it will clog almost before I pull the trigger
