Hey. I'm still fairly new to vaping, started out with a 901 about a month ago and have now moved on to the 510 which I prefer by far. I've gotten into direct dripping now and don't think I can go back to using carts. My only problem is everytime I take the empty cart off to direct drip there's juice all over the end of the cart that fits into the atty. I have to wipe it down everytime otherwise when I push it back on the juice comes out to the outside of the atty. Am I doing something wrong and is there any way to avoid this? I've also noticed the cart seems to make a gurgling sound a lot of the time, I'm guessing the juice is getting down into the cart.
