Badger airbrush problem

[archerwin]

I have a Badger 100 GXF gravity feed. The paint is bubbling back in the paint cup. I have been suffering for a few months now. Last night, I thoroughly cleaned all the nooks and crannies, including the small holes. Unfortunately, it still bubbles back. There's no stuck paint in the nozzle and the needle is clean. I've checked the seal of the nozzle head to the main body and there's no leak. The paints are properly thinned, even with just spraying water or future I see bubbles comming from the paint cup... What's the problem? HELP! thanks in advance!

I have an old-style 200 and a 100G. If plain water bubbles, there's still some dried paint crud somewhere in the very front of the brush. I suggest taking the head/nozzle and aircap and soaking them in some acetone for a little while and then really clean that nozzle and the hole in the aircap out with a fine wire or an old needle. But don't soak the white washer that goes between the head and the body, just the metal parts.

i'll try again if there are still some dried paints. I know I cleaned it thoroughly last night. I soaked the metal parts in acrylic thinner for a good 30 mins before scrubbing w/ fine dental brushes

Try soaking in laquer thinner, not acrylic thinner.

Wow! I was able to fix my airbrush!

So I was right that there were no dried up paint in the nozzle... after further examination, the gunk or contaminants were actually coming from the needle bearing part (in the airbrush main body). It was being drawn to the tip whenever I re-insert the needle after cleaning. I wasn't able to see it before :( :(... maybe that's why there were some rusts already forming in the part of the needle. It was because of the contaminants already sticky in the needle bearing. After thorough cleaning, it was good as new! I also applied beeswax on the threads of the head, crown and the tip itself. Also applied beeswax on the periphery of the head where it mates with the body. overall i'm satisfied! no more annoying paint bubbles and sudden spurt of paint I was really ready to give up on my trusty old badger. Good thing I read up on many many forums to find a good solution. Moral of the story... look for and fix the obvious but if it doesn't work be ready to explore to find the solution you need :unsure:
