Loose airflow adjustment screws on EHPro KFL Plus

[Flt Simulation]

Anyone here have there small airflow adjustment screws on the bottom of there kayfun Lite-Plus change there position over time because the screw's threads are loosely fitting in the threads of the atomizers base?

I just bought a EHPro KFL clone that has the dual airflow adjustment screws in the base. I set each screw to 2 turns out from the fully seated position. A couple of days later, these screws had both unscrewed themselves out much more resulting in too much airflow for my style of vaping.

The only fix for me was to screw one of them all the way in (closed position) tightly, so it could not ever unscrew by itself ... The other screw was just removed. This combo resulted in the right airflow for me.

Other than that, this EHPro KFL Plus clone has been a real pleasure to vape with NO leaking, gurgling or flooding ever.

In fact, I like it much better than the authentic svoemesto Kayfun Lite-Plus V2 that it replaced (the authentic would at times leak, gurgle or flood).

My EHPro Kayfun 3.1 has one air port and another beside it with a screw that's used to regulate air flow in the first port. To make a difference the screw has to be almost all the way in, since the two ports converge and the screw blocks the actual air hole when it's almost all the way in.

The adjustment screw on my 3.1 stays all the way out and it tends to screw itself in from the negative pressure when I take a hit. Over a week's time it will start to recede into the hole. I just back it out again. I recently inserted a tiny piece of kraft paper into the hole, screwed the set screw flush and tore off the remaining. That locked the screw on the outer end of the threads where I can remove it any time.

Thanks Dave ...

I might still have a small tube of blue thread lock out in the garage. I will give it a try.

But, one screw all the way in tight, and one screw removed does give a good airflow for me.

My bigest problem was that air flow control screw would loosen up and make it almost impossible to take the KFL off the MOD because the AFC screw would get stuck in one of the air slots cut into the top of 510 connector of the MOD.
I used a bit of teflon tape on mine and the adjustment hasn't changed in the 2 years I've been using it this way.
