Ok, so i decided to try out a carto/tank setup, long story short, i screwed the carto on too tight, and trying to take it off i got off everything except the last little bottom piece, and it refuses to come out, the center pin just keeps turning and turning, is it hopeless? i am stuck using a lambo 4.0 now which is fine except for horrible airflow with my vivi novas... >_<
any ideas, please see pic.
