I picked up a 306 atty and drip tip from good prophets recently and am having trouble with it. I've used LR 510's before with great results. I'm using these on my ego. The 306 produces almost no vapor with any of the juices I've used, which were all different kinds of vp/pg blends. Little smoke, very hot, almost no flavor. I've debridged my 510's in the past and loved the result so I debridged the 306. Didn't help at all. It would also get so hot that the juice would boil I guess and start spitting out of the tip into my mouth. Any suggestions or did I get a bad unit?
