Thanks AG. I changed it once more last night and today it seems to be
vaping good again. I think I was choking the coil. Don't know why, cause I been running it for the last two weeks or so without any probs at all.
I was surprised tho that my set up is almost identical to yours. 0.5 coil, wicked about 1/4 way into tank and using the ceramic block too. Not a cloud chaser either. And been building the ID of coil at 3mm, seems a bit easier to wick at that diameter.
Have to say I'm really loving this thing!
Thanks again for the inputs...
