I am regretting just buying the Ego One battery and not the whole kit because it is not making a good connection with the sub-tank nano. When the tank is screwed all the way down on it won't fire. I have the loosen it a little to find the sweet spot for it to fire. I have tried pushing the pin further out of the bottom of the tank and I used a deoxit gold and neither have helped. Any suggestions. Thanks.
