Typical e-liquids are 80PG/20VG or 70PG/30Vg.... cartos, clearos etc are not setup by default to handle much thicker ones. To address this type of issue... you either have to thin the e-liquid a little or thin down the wicks a little...
On the Evod's ... using a 30PG/70VG juice... I remove one of the flavor wicks to avoid dry hits... Not sure what the equivalent is for a Raven so if you thin the wick to help.. do it slowly otherwise you end up getting the gurgle again and possible leaks as well.
