Evod choked not clogged, extremely weird. HELP PLEASE!

[workingpapi]

I consider myself pretty new to vaping but already have some good knowledge, I build my own coils and have become kinda good at cotton wicking.

ISSUE: Today something extremely weird and new happened (and when I say new is a lot cause I have experienced thousands of issues new vapers go through and have learned to avoid them)

As I am drawing the air tube becomes constricted, choked .. NO LIQUID coming to my mouth, of course I ensured the air holes are completely clean and unblocked, the airhole on the center coil pin is also clean, unblocked but even with the evod unscrewed from the battery as I draw it starts choking until it feels like vacuum pressured eventually as I was drawing it felt like a bubble bursted and the liquid was vacuumed into the air tube. I tried my aerotank later tonight and it started feeling the same ... after wiggling the coils and wicks around it feels normal for now, but I have been making my own builds for a very good time now and this had never happened... wicks are not big, they are loose enough, no gurgling just that weird thing that feels like vacuum pressure. What can be possibly happening??

In case it matters I was using a 2mm coil, 30awg kanthal, 2.4ohms at 3,9 volts. Cotton wick that had worked awesomely for about 2 days of continuos vaping

Thanks in advance.

Have no fear, I is here! You can't see it, but you're missing an awesome pose.

Assuming you don't actually *want* liquid coming into your mouth (I don't judge), what I think is happening is the little rubber/silicone insulator at the base of your coil that you put the pin into is squashing out as it wears out. Because of that, it's expanding outwards when you put the pin in and/or tighten it down. As it expands outwards, it is hitting the sides of the wall and creating a seal so no air can get drawn up. There are a few places you can buy replacements for these, though in a pinch you can trim them but you're kinda playing with fire in terms of shorts/leaks/NON-readings.

*gives the horns*

Thanks @drunkenbatman! I´ll look into that! Makes perfect sense now that you say it, because I´ve been using the same rubber stopper for a good while now on all my builds on that evod.

another way of avoiding squishing it, dont tighten the tank onto the battery, just finger tight till you FEEL the centerpost make connection.


i too rebuild protank heads, and at this point in time, out of 13~ coil heads that i always switch when rebuilding, i probbably have 2 with "FRESH" grommets.


as stated above, you CAN trim the rubber, but i personaly do not sudjest it, as the second the rubber is cut it seems to "rip" from the cut and make things worse.


ETA: also from the sounds of it, you might need a new wick. your sounds gunked to the point of over saturation due to coil crud

woot! If you get stuck finding them send me a note and I'll pass on a few places that've worked for me where it's more cost-effective in bulk. Like o-rings they're just one of the parts that'll eventually go south on them, either via going squat or tearing.

Happy New Year!
