Your issue is you flooded the cart once, and now its staying that way. Heres a little known secret.
Take that 510 cart, mouthpiece end, slip you a paperclip or something in the hole, and give it a pull. The end cap will come off. Look inside..its probably a nice pool of juice, and thats what your sucking up. paper towel that bit out. Looking in now its a chamber with another lil hole...stick a paperclip in THAT hole, and pull up. Itll pop out too. Its a little disk that is supposed to keep liquid down, but it doesnt. When you pull hard on a flooded cart or atty, you just create more pressure in there, and it will pull liquid into that chamber. Chuck the disk. Put end cap back on. Now if you ever get liquid comming back at you, just blow it right back, lightly, to the atty.
I havent seen many, if any posts on this, hope it helps.
