Sounds like your larger seal on the coil is not sealing off the tank from the battery properly. I've had a couple of evods come in and found the coil loose from the ego threaded base, which will result in leaking, gurgling, etc... Once you put the coil back on the base, check the seal between the two visually to see if they are meshed tight with no gap. Other than that, I would go back to the store and have them either put in a new coil or have them give me one to try and determine if thats the problem (defect). From my experience with evods, a 1.8 ohm to a 2.0 ohm coil works best with the spinners or twist between 3.7V and 3.9V in my opinion.
