EVOD's - What am i doing wrong??

[anthonyb]

Im sure there's only one flavour wick in the heads I have. I'll double check. Will removing completely not flood the thing? seems like theres plenty of room for the juice to migrate into the centre hole if they are removed??

I would say it's gunking that's more like the problem.
I run 4 evods with different juices in each, on a daily basis.
All are recoiled on sunday night, ready for the week ahead. I use 3mm silica wick with 2x 1mm silica juice wicks. And 5 turns of .25 kanthal,. Some of the evods will last all week,(or more) at least 1 will need a clean or recoil (usually have spare heads ready) within a couple of days, due to gunking.
You might want to get some extra heads, and have a go at recoiling. It can be a fiddly, but works out dirt cheap, and you know you have a nice clean head.
Some say, what a waste, but personally I can't be asked to clean and dry burn. I find it easier to just change it.
Plus you can adjust the ohms to suit as well.
