Update: This is after the second 2.5 hour burn,I'm thinking already that it's overwicked,lots of puffing black smoke,actually caught some in the pic I do like how its keeping the side of the jar fairly clean which is the reason I went from Eco10 to Eco12,the other pic is one that I've had burning with an Eco10 and as you can see there is alot of wax being left on the side of the jar, Thoughts?
