I fixed my leaky problems by using a 6ml bottle cap o-ring between catch cup and base of atty. Stopped all leaking at the base. Also gives you better control over positioning of the air hole. You have to screw the base down tight so it fires but the coil, and air hole on the cap are just a bit counter clockwise of where you want it to be. Then put the cap on and turn it until it's perfect. One advantage is you can unscrew the cap easily without unscrewing the base. Next up was the leak accumulating where the caps threads down on the base. Normally liquid would seep out overnight so I make sure I don't get that gurgle when blind squonking when I go to bed. Normally don't have issues with the air hole unless I just left too much juice in it. So again, I make sure it doesn't gurgle when I put it in my pocket. Using these methods I don't have problems anymore...
