Learn to backflush with the acetone. After you've soaked the air brush in acetone, fill the cup with acetone, put your finger over the nozzle to block the acetone/air mix from coming out. Pull the trigger all the way back, and down, to force the mixture back up through the paint cup. Do that for ten seconds. Then loosen the nozzle assembly one turn+- and back flush again the same way. This will force the mix back through the tiny hose that the paint passes through. Then loosen the needle, remove it and wipe it clean WITHOUT bending it or dulling the tip. Br gentle and take your time to get it out and back in straight. Put the needle back in, and repeat the backflush with clean water. If that doesn't clean out any remaining dried paint, I don't know what else to do. It always works for me.

i use a small brush (like for model cars) to wipe mine after a use a wire brush made to clean airbrushes with, as well as a thin rag or a paper shop towel. How long has it been since you replaced the needle and/or nozzle on the old one? They are considered "wear" items, and may just be worn out possibly if you feel they got cleaned well. The new one sounds like it still has some paint chunks in the tip causing blowback or the needle isnt fully set in the nozzle and/or isnt seating properly in it due to possibly wear or paint residue in them. It could also be the acetone itself causing the problem. If the seals in your airbrush are not rated for solvents, the acetone may can eat them away and cause problems with the airflow. I use a light amount of acetone on mine sometimes when cleaning and after breaking them down, but if they need to soak i use airbrush restorer from auto air instead.
