Dual coils are not ideal to learn with imo.
When you have the wick removed pulse the mod and observe how the coils are heating.
They should heat from the center out and evenly for both coils.
I agree with eddiea it appears that there is not quite enough cotton.
However if the coils are not right no amount of wicking will fix it.
