Air Filter Leak

[Kgkatyag]

Hi y'all, im working on this 1941 Super Deluxe. It has the oil bath air filter, but it seems to be leaking out of somewhere and getting oill all over the carb. Even with almost zero oil in it, its leaking.
I'm not super familiar with these, so I am hoping one of you could point out where the leak is coming from or have some suggestions.
Here's some pics of the air hat and my carb after I started cleaning it

thanks
