Everyone else who already replied knows much more about this than me but I thought I would chime in real quick. I just got a ZAP myself and I was having a miserable time getting Boba's Bounty (100% VG) wicking with the pre-installed 400x400 wick. I went ahead and removed the pre-installed wick and coil and switched over to one of the 325x325 wicks that was included - this solved my problem completely and I didn't need to remove the insulator. It is important to note that the coil that was pre-installed was at about 1.8 ohms and the one I wrapped myself is 2.3 ohms. I actually prefer the resistance to be at about 3.0 ohms so I ordered kanthal in gauges that will allow me to do that with the same number of wraps.
I have noticed that I need to dry burn the coil to get gunk off about once a day and I attribute this to the 100% VG juice I use. I have also needed to adjust the coil a couple times when hot spots cropped up so it may be worth trying that. I am learning that coil maintenance is just part of using a Genesis style atomizer.
I am completely new at this but my advice would be to try to work with the materials supplied with the ZAP until you get the results you are looking for. On my first day with the device I got tremendously frustrated but all was well with a little tinkering. Best of luck to you!
I did the EXACT same thing. VG wasn't wicking with the installed 400 wick, so I tore it out, put in my bag of spare parts, and made a new wick and coil using the 325, but it STILL will NOT wick VG juices. I'm going to try taking the insulator out. I do really appreciate your post though because it shows that I'm not the only one with this problem that was able to fix it without buying more stuff.
I just switched out the 400 ss mesh for 325 ss mesh. Left the insulator in and wrapped my coil using the drill bit method. Also I unwrapped Zens 325 mesh and made it a bit thicker. Also oxidized it some more. Put some 100% VG juice into it and currently having a fantastic vape. Very smooth and no dry hits.
Just curious what you mean by short-cut though? I'm also new to genesis atomizers and want to use them to there full capabilities.
I'm afraid to unwrap the included wicks because I don't have the funds to replace them. Is this something I should do?
