That should be adjusted to give the amount of paint you need (how far the needle opens).
I'm waiting on a new airbrush any day now.
My gun has a adj screw under the paint cup as well . So how should they both be adjusted ?. Should i selt the neddle for max throw & fine tune with the paint cup adj screw ?. You can see both needles in this pic .
Well i did my first airbrush paint job. I think it looks pretty good for the first one . I dont know how to post pics . So if someone could host or post it for me please let me know . I used fascolor water based paint . also to anyone that uses fascolor paint . what do you use to thin the paint, & how much do you thin it ?. I used the fascolor thinner . but i've heard people use windex or alchol as well .
