So, I was lucky enough not to have issues with dry hits, or vapor locks or anything similar. I'm having a single issue with my killer in tank setup.
If I open the liquid regulator over 1/3, the central post which is mobile to ensure proper contact gets pushed in by the contact pin of the head of the PV, meaning it screws down further this covering the air hole. The result is a stiffer draw (which does not really bother me tbh) and a whistling noise while vaping.
A few pics to explain the issue (I used an eGo/510 adapter for clearer pics):
Fully closed, the central post is almost protruding:
And the result is that the killer/tank air intake sits nicely above the edge of the connector:
If I open the liquid feed and screw the system on the vp, the center post gets pushed in:
Resulting in a completeley covered air hole:
Anyone spotted this? With thinner liquids I can cope with the small aperture of the liquid feeds but with my 100% VG, I'm getting bad liquid feeding/dry hits.
Suggestions for a fix? I hate the "whistling" sound it makes...:/
