Hi guys, I've been having this problem for a while. My airbrush is one of those really cheap, consider that it doesn't have an "air only" function. The actuator only spray/doesn't spray, and air always comes out. Said that, after using it a bit, drops start to form in the nozzle. When I clean it, I also see that the needle is all dirty. I'm worried that something is leaking. While cleaning it, I pulled out the gasket I'm showing in the photo. I don't know if it goes under the needle or above the needle. I don't know if the problem is this worn gasket. I'm thinking of replacing it.

Can anyone help me? (Buying a better airbrush isn't a solution. 😅)

Thanks all
