running dual coils with 24g at 0.22 ohms. ive tried many different builds and they all do the same thing. It's not running too hot. Even at 0.40 ohms it happens. After a few hits, the cotton needs swapped out or I have to clean the coils and replace cotton. It's just frustrating bc it takes too much time to mess with. thanks for the positive feedback to those who gave it.
1. try building single coil, less fuss, higher resistance. Most RDAs allow you close off one side to work in single coil mode. You can tinker faster only doing half the build.
2. make sure cotton (or other wicking material) is not too tight in the coils or it constricts wicking, and not too loose.
3. make sure air holes line up to coil(s), you need clean air flow path across coil(s), or you just burn juice instead of vaporizing it.
4. try a different juice. Some darker ones really gunk coils after a few ml, but not after a few hits.
