I broke the glass on my V2 so decided to give the V4 a try....
I read and watched all the coil and wick set up recommended and attempted to do the same but used a cotton yarn instead of just cotton ball. I didn't work probably due to the difference in density and physical property. So instead, I tried to set it up like I would my Fogger V2 and it works great!
1) I used a slightly bigger drill bit to wrap my coils (probably one size bigger) and wrapped it 6 times.
2) Then I passed 4 strands of 3 mm cotton yarn through my coils. It's snug but not choking tight.
3) Instead of trying to fit one strand per channel, I just left the channels alone. I trimmed my cotton yarn short enough where it fits nice and snug around the chimney ring with each of strands from the 2 coils making a full circle coverage (the length coincided roughly with the length you would cut it to fit in the channel)
4) The first time tried with the chimney screwed on tight, I was getting some dry hits between puffs. So I tried what I used to do with the V2... Instead of screwing the chimney tight, I used it to control the juice flow. I unscrewed the chimney 2 full circles. Now my wicks are getting the proper amount of juice, no dry hits, and no leaks.
It's a bit tricky screwing back the top cap with your chimney not fully tightened. What worked for me was pressing down the drip tip and holding the chimney down while screwing the cap.
Hope this info helps other who want to experiment a different set up for the Fogger V4.
