This is not directed at anyone in particular, but I honestly believe some people are over-saturating their Crown coils initially and that is leading them to issues. This is how I saturate mine with not a drop over or under:
Not sure how much this is as I eyeball it. It's probably about a 1/3 of a mL or so. I just drip onto a plastic surface (the lines are my guides of sorts and I've used that card ever since I got my amount right. It's just a 3" x 5" card under the plastic surface). Note: it takes way less liquid than it seems it would.
Place the coil head on the little puddle with
one liquid feed hole facing directly down into the puddle. You can get the idea of how much (or better yet, how little liquid) is used by seeing it in relation to the coil head.
About 10 minutes later and the liquid is already pretty soaked up, but it's not made its way up and around into the cotton yet...
Exactly 15 minutes later (generally all that it will take for 70 VG, but 90 VG takes about 20 minutes or longer). The liquid has made its way up and around and it's saturated fully.
25 minutes later and no more liquid would absorb. That last little drop is what would not be absorbed.
Perfectly saturated with no more or no less than it should be. This is what I do to ensure no gurgling, no flooding, no excessive spitting and no wonky hits from drowning coils.
Everyone has their on way to do it, so this is only here for someone to try if they are having issues and would like to try a new method. Note: once placing the coil on the puddle, don't fiddle with it. Leave it be and trust that cotton will do what it is supposed to do, i.e., absorb. I don't rush the process.
