Sounds like flooding... if it gurgles, there's too much juice in the coil. Take the clearo off, check your battery connection for juice, then put a paper towel over the threaded end of the clearo and blow gently into the mouthpiece to clear the center tube of excess juice. Reassemble, and remember to take slow, gentle draws... if you hit it like a cigarette, you'll pull more juice into the center and flood it again.
