Using it without squonking, and with the included plug for the hole on the 510. The 510 isn't adjustable. To my surprise juice is leaking into my mods 510, through the o ring on the 510 pin. It's not pouring out, but using it on a mech doesn't seem safe, so it's on the shelf now. Which sucks! Anyone else have this problem? Thanks for any tips to stop it in advance.
