Ok, so I have a few 801 style atomizers. They don't seem to pull the liquid from the carts.(I think bad carts) I have been dripping. Now one atomizer is dead, the others slowly stop producing good amounts of vapor after a few drips. I use the atomizers til they stop producing a lot of vapor, add about 3 - 4 drips of liquid and the more times I do this, the crappier the vapor is. I have blown them out and dried them, reprimed them and no go. I have no way to try and boil them since I am on the road all the time. Any idea's?
