PSA: Check your KFL/Russian chimney orientation.

[0S1R1S]

I made a tutorial for a Kayfun build over on Reddit and it seemed a lot of people didn't know about this:

The chimney base on your KFL/Russian has two different ends: One is tapered, and the other is cut even.

Use the tapered end down to allow slightly more juice to pull through the channels, thus fixing dry hits.

Some authentic and clone users both reported having a tapered end, while some had no tapered end at all.

Great tip! I never noticed, thanks.

I have an authentic kfl+v2. when I rewick in a few days, I'll check it out.

Not a Taper.
That is a reduced section. When used in the up position can support an o-ring without causing the chimney to be raised. O-ring reduces chance of drawing fluid through the threading into the inner chamber, a possible problem with thinner e-liquids.

I have 2 Kayfuns that came with the grooved chimney and the o-ring already installed on the top section.

I definitely noticed that the second or third time I rebuilt my KFL. I was wondering why it was like that.
