long story short, something come up yesterday, so I didn't soak. I just cleaned airbrush and stuff and put it away. Today no paint come out. Tried with cleaner, No cleaner come out. I tried on steady 10 psi. I changed nozzle and needle and it worked normal on 10 psi. So I removed ''new needle'' and put back the one which I didn't soak, It sprayed normal. I put back old ''unsoaked'' nozzle and it didn't spray again. So I know it is a problem in nozzle. I up-ed the pressure to 45 psi and it sprayed normal with ''unsoaked'' nozzle and needle. Then I soaked nozzle for one hour, clean it and try it again. No luck. Inspected with magnifier it doesn't look cracked not flared. When I look inside of it it looks clean and I can see from one end to other without problem. So I just soaked that nozzle to see what will happen tomorow with it, but I am still wondering do I miss something. I sprayed at 10 steady psi cleaner, but when I spray paint i use 10 drops paint and 50 drops reducer. It works. Until today. Am I missing something? thx for help.
