Russian 91% air bubble/burnt taste

[Zanzabar78]

Hello everyone,

I have a Russian 91%, its great except for this one nagging issue.

Every hour or two, I start getting a burnt taste. I unscrew the top a little until one or two air bubbles pop up and viola its resolved for an hour or two.

I use the top fill method to fill the device: fill, cover airhole, screw a bit, flip, close, remove finger from airhole.

Any ideas what I could do to resolve this issue or is it normal? thank you

whats the pg/vg ratio of your juice? what is the type of wick you are using? pics of your coil would greatly help if you can manage to post them too.

PG ratio is 70/30, silica wick. Phone camera busted unfortunately. Like i said it works fine for a couple hours, then have to open it up a bit and release air bubbles

The problem is that ejuice is not being drawn up the juice chanels. A thicker ejuice with more PG can exacerbate the issue. Short term fix: without firing, give a couple of quick hard air draws to bring the ejuice into the chamber and wet the wick. You'll see the bubbles.

Of my 8 Kayfun I had one that would constantly dry out easily and after many rebuids found that a build using the next lower gauge (large) wire solved the issues. Sometime the ejuice chanels are not bored out enough as well but I did not feel like fooling around with a Dremel.

That shouldn't matter too much.

I vape very high VG and I have never had wicking problems with the Kayfun.

I would highly advise messing around with your wicking before you start buying new kanthal and busting out the dremel. This problem can likely be solved by a quick tweak to the wick. Dry hits are a good indication that you're using too much cotton.
