I have a Joye 510 and there is a little silicone ring in the cart under the mouthpiece. It is under the small cap. What is it and what does it do? Mine keeps getting turned sideways and I push it flat every so often. How deep should it be set in the cart? Thanks for the help.
The 510 cart is partitioned into two sections: that which holds the liquid, and that which the air pulls
through into the mouth. The air intake vents are on the side of the cart, like whistle holes. The air does
not go
through the filler, it goes around the filler partition on either side through the vents, inside, and through the little Si ring you mention, like two funnels with one end. If that ring is always having to be put right, I think its time to use a new cart, although
vaping might not change much even if it is removed. Never had a problem like this with any of my 510 carts. Seems like the one you describe was poorly constructed from the beginning.
Hope this helps!
