I have an eleaf ikon 220 with a crown 3 tank. Got a semi-dry hit off of it and figured it was time to change the coils. Did this, primed the coils, put it in, made sure the juice was good in it, turned off the air and sucked through the top without triggering it. Still got a dry hit from it after this. It's been sitting for an hour and I'd think the cotton would be pretty good right now. Any thoughts?
