sputtering brush

[half fast]

I used my brush 2 days ago and it was working good. I thought I cleaned it out real good, but I guess that my not be the case.
When I went to use it to-day it would sputter the paint out. I also had to pull the trigger back a good bit to get the paint flowing.
I,m using a new vega2000. I,m assuming that something is clogged or dirty,I tried cleaning it out 4-5 times,but to no advail.

What kind of paint are you using?
How thick is the paint you are using?
Are you painting in the extreme cold?
What air pressure are you using?

Ideally, you would like to have paint at about the viscosity of skim milk, but that isn't always possible, so you need to increase the air pressure to make the paint atomize/spray.
If you are working with water based paints, then painting in the extreme cold can cause problems too. The water in the paint can freeze up, making your paint hard or like a thick mud.
Make sure your paint is properly reduced with the correct reducer/thinning agent, and that is is well mixed and strained before putting it into your airbrush.
If you are using a siphon feed brush with a bottle or jar mounted below, make sure that the vent hole is free and clear of any obstructions, and that the feeder tube and female receiver on the brush are also clean and clear of any paint or debris before you start. If the bottle doesn't seal tight, then your brush pulls air from around the female receiver rather than pulling paint up through the feeder tube in the bottle itself.
Also make sure your brush is clean before you start, make sure that there is no debris in either the body of the brush, the nozzle, or the needle cap.

All this is general advice, whether it solves your problem or not, I can't tell until I have more information from you.
Good luck!

ya may have to soak yer brush for a few hours in cleaning solution, and then clean it as usual, Frank. Sounds like it's just dirty, or ya may check the needle and where it is sitting in relation to the needle tip, if its sitting to far behind it, it will sputter. Do ya have a filter on your compressor or in line ? If ya don't have one, that could be another reason for your problem. Your paint may need to be thined or the psi may need to be adjusted.
Hope these sugestions help. ( Fontgeek, ya posted about one second before I did LOL )

The tempt. in the room is about 75. The psi is 35. the paint is food coloring,and water. I will check out the vent in the jar shortly.
Thank you for your help. I hope that this will solve my problem.
I will let you know.

I checked the vent it was ok. I then put the bottle back on and tried it, as I watched the jar.
while holding the air on bubbles were forming in the jar. Then the siphon started when I applied paint, then stopped and started. It wouldn't keep a siphon continually??? Again thank you for your help.

Bubbles in the cup or jar usually means that you have a blocked Needle cap or the threads on the nozzle are letting air leak through. Check to make sure the nozzle and nozzle cap are clean & clear. If that doesn't solve your problem, try applying beeswax to the threads of the nozzle. That should stop the leaks.

I finally found the parts list, and it looks like there is suppose to be an O ring in the air cap. I don't have one anywhere near it so I'll order 1 or 2.
From the advice you all have given (air leaking at the nozzle) this will probably take care of the problem. I will let you know when I get the O rings.
thanks again for your help.

Half fast, if your brush is new, then it probably got missed by QC by the airbrush manufacturer, not good, but not the end of the world either.
Hopefully that will be the only thing they missed.

If your brush still acts up, then I would send it back for a replacement, or get a different brand all together.
