Hey guys! thanks for your replies. I'm sorry I wasn't very helpful with my information.
Yes it's an iwata CR, and I opted for the 3mm needle.
The paints I'm using are for miniature painting, Model Colour theyre called. Not tube acrylics. Also, acrylic inks. I water them down using water and alcohol.
I do occasionally get bubbles in the cup, but I'm not putting hardly any paint in the cup so it can't be overfilled.
I can spray water, and I can spray the paint just fine, but occasionally is blocks and then spurts out a lot.
When I received the airbrush, I had this issue, so i took it to my local art shop and the guy ordered a new nozzle and installed it for me. But if you think its the nozzle being blocked then I don't know what else I can do!
I'm following tutorials on how to use it, doing everything correctly as I'm told.
Thanks for the help, I hope this clears up any doubts about my equipment and paint choices.
Thanks!! This is an awesome forum!
