I’m trying to paint a feathered camo scheme and can’t seem to keep my airbrush from spitting. I have adjusted the thickness of the paint, air pressure and trigger amount and I keep getting spitting. This hasn’t been a major problem before as I usually mask and it wasn’t as bad as this earlier.
I’m using a Badger 105 and MM enamel.

Bent needle or nozzle perhaps?
Hmmm, I’ll have to take a look at it, that may be it.
Often thats water, which the compressor forces into liquid from air.
If you don’t have one, get a water trap.
Partially clogged nozzle will do that - just had it happen a couple days ago.
I get spitting from a dirty nozzle- incomplete cleaning from a previous session.
I got spitting from not installing a needle correctly, make sure the needle is pushed all the way in and that the paint tip is the correct size to fit it snuggly.
Damaged packing nut will cause that also.
After looking at the needle under a magnifier I noticed it was a little bent. I ordered a new on so I can get to my camo in about a week or so. We’ll see if that does the trick.

The needle can be fixed…
I tried, if nothing else I’ll have a spare. I should get the new on in 2 to 3 days and I wasn’t much.
I had a similar situation recently with one of my airbrushes. After really magnifying the tip of the needle, I found that there was, what looked like a tiny hook or split in the very tip of the needle, this had collected a small fiber which was collecting paint as the paint was sprayed and the paint would come off that fiber as chuncks or globs onto the paint.
I too had spitting problems. Upon examining the paint tip under a magnifying glass, I noticed a slight crack in the tip. Replacing the tip solved the problem.
I received my new tip the other day, and while it’s not perfect, I believe most of my present problem is the paint consistency and pressure. Just need to find the secret sauce.
That is an ancient Chinese secret… LOL! I couldn’t resist saying that.

Try lubricating the needle. This also helps with the tip dry problem.
I had this problem yesterday morning while pre-shading. It just started with my Badger 200 about 5 minutes into the paint session with a mixture ratio I had used many times and a good needle. The cuplrit? Humidity was at about 60% in my basement and I had my moisture trap on the hose for my Paasche VL. Once I put the trap on the hose for the Badger and cycled some thinner through the unit, the problem went away. Other then that, its usually the paint is too thick for the needle setting or I am ham fisting the trigger while being to close to the surface.
I believe my problem was the slightly bent needle…and just trying to get the right concoction of thinner and pressure. Humidity isn’t too much of a problem here in Boise. Typically fairly low in the semi-arid high desert.
