My first mod to the round cart (510) was to saw off most of the tip that is inserted into the atomizer. This prevents the narrow airway from extending down close to the metal mesh and keeps juice from being sucked up into the outer chamber.
No more juice in the mouth, no more juice in the resivoir just below the mouthpiece.
Someone pointed out that with the round carts, the flat circle at the mouthpiece can be popped off. Below this is another flat circle with a hole in the center... that can also be popped out. And below that you can see the rectangle shape that holds the fiber.
I held the cart with a pair of pliers and drilled the rectangle shaped plastic out completely, and cleaned it up with a small file. Now I've got what is essentially a plastic tube I can drip into.
This mod may have been mentioned before but I thought I would post it since it has made dripping even easier for me.
