I've been using a IGO-L for a while now. Love it. I set it up with micro coils and cotton. Hard to tell from your pics, but I don't think your coil is a proper micro. Super_X_drifter has a great video on making micro coils here. IMO if you make yours the same as he does you will have success. Just leave the tails of the wick a bit longer as you are not bottom feeding like he does.
1.2 ohm 28g kanthal 5/6 wrap on mini screwdriver
I spaced it out instead of touching ... juice don't burn up as fast on cotton wick
less than 1 ohm I use a mech... patience practice trial and error = great pay off
flavor and vapor 10x better ... it holds a good amount of juice
Ok, a few things.
Your air hole looks huge, is that 1/8"? Not much can be done about that now but I like about 1.2mm for a good balance of vapor and flavor.
What did you wrap your coil around, it looks bigger than 1/16" which is the biggest I would go for a true micro coil. It also looks like some of your wraps might be overlapping instead of side by side.
Do you have 30g kanthal? 28 takes longer to heat up >1ohm, which you have to be to use on a regulated mod, could try cranking up the volts a bit, but 30g would work better.
Your wick does look a little thick, it might be choking, and not feeding the coil properly.
Try to align your coil directly up with your air hole both horizontally and vertically, and get your coil as close to the hole as possible without it touching.
Hope some of that helps, the link posted before to super_x_drifter's vid should help, he's the micro coil guru.

Micro Coil On A Trident RDA - YouTube
i used micro coil also but it tends to burn juice way too fast ........ but this is the youtube guide i used to build it... i did not use a torch= i used my stove using the blue flame held with a long nose pliers... really easy especially using 28 g kanthal...
so now i use similar steps but instead of touching/stuck together i space it evenly and still use cotton ball wick
Looks like your coil is "choked"....a bit thinner wick may help..
Are you using 100% VG juice???? That thick juice will NOT wick as well as, say, a 50/50 PG/VG.....
And...especially if it's COTTON....the wick MUST be saturated!!!
I just started last week dripping with an IGO-L...2.0 ohm coil, air hole drilled to 3/32"....after changing out the silica wick to cotton (Peaches & Cream from Wal-Mart....) it's all good!! Boba's Bounty, dripped, is AMAZING!!! (But 24mg nic can have you "star-gazing" before you know it!! Kinda like the difference between putting something in your nose vs into your vein....)
Don't give up on the IGO-L....or dripping, period!! Someone else mentioned the 510 (bridgeless) dripping attys....I have several , and they work really well....just need to CLEAN 'em up after each use.....
Happy (vaping) Trails!
