Ok, so I'm a noob. I know. I bought a m301 from litecig about a month ago to quit my chew habit. I instantly loved vaping. MY only problem with it was the battery life and juice capacity, So I did some research, and stepped up to the ego. I ordered the starter kit, ego mega carts and mega atty (4 of the attys), and a cartomizer. The 510s and carto was great, but when I used the mega atty & cart I get gurrgling most of the time. Dosent matter if I put 10 drops or 40 in the cart. I added more vg to the mix, didnt help much. I blow it out, it stops till I put the cart back on. As soon as I do, it does it again. Any ideas?
