Omni 4000 Problem...

The needle is not far enough out, probably from where you cleaned it last. Loosen the chuck at the back of the needle, push it forward until it just seats against the nozzle, tighten the chuck.

I agree with MusicCity , it is because the needle is not in the nozzle properly which will happen after cleaning if you don't push it in properly! You should use lube to lube up your needle this makes tip drying paint to not happen and helps with the spray to come out cleaner.

Thanks guys, I'll give that a try. Don't have any lube though. Guess I need to try to find some.

Yup, that seemed to have fixed it. Thanks.

Mine did the exact same thing when I first cleaned it.

All part of the learning curve.
