I just switched to a new atomizer as my other one wasn't producing like it should, I will try and clean it tomorrow.
Anyway, with the new one, I am getting that burnt metallic taste. I tried a couple of different carts. When I go back to the old atty, the metallic taste is not there. Not sure what is going on here. I had this once before with a 401 atty, and it finally got better with time. I hope this one does. I am going to set it aside and break out yet another new one and see what it does.
