hello everyone! first i will say, sorry for my English. i have H&S ultra with 0.2mm set, using createx colors and model air . my problem is that every few seconds there is paint build on the midway top of the needle. it is closer to the tip then the nozzle. i have tried several options of reduction ratio (4012), added 4030 , tried different psi 10-35 and no matter what , the paint dry on my needle after 10-30 seconds and i cant paint until i remove it with my fingers or qbud. or just make a big trigger pull back. i checked the needle for bent , the nozzle is clean with no cracks (i use airbrush cleaner , H&S nozzle clean device , dental brush). i need help please. thank you all and i am happy to join this family!
