Hot spot is good sign, it's an alarm, it telling you that there's short between coil and mesh. Try using the methods I've post early in this thread, drill bit method or rolling paper(cigarette paper) method, try either one of them that you think easier for you.
I always using drill bit method, cause is it easier when you need cleaning the coil and mesh. Just simple pull out the mesh and torch it again, and for the coil still in place on the atomizer, just fire the coil hot red few times will clean off the mess. Then put the mesh back in the coil and reuse again. I can reuse them(coil & mesh) up 4 - 6 times until the resistance of the coil dropped down. (And, that's why you need an APV with ohms reading. Thanks to VV gripper and Vamo!

)
Btw, I also use the "dual wick method" for my mesh wicking like this one:
With this, WOW! Never get dry hit again!
For the hot spot issue, you need to learn and experience it. I also have trial & error many times when I first start using genesis RBA. Now I can easily solved this issue in just 1 or 2 minutes. Never try to get away the hot spot via using add washer or add twist at the lead like this:
Twist lead. (Actually I did this, but I given up already.)
or Add washer
Although it did solves the hot spot issue, but this means you've ignored the alarm, and the resistance might be shorter, something you will taste burning iron... Just keep learning and trying, until the coil heat up hot red from the center not from the lead like this:
Just like it heat up hot red exactly the same when the mesh is not there, like this:
Tell you what, I learnt all this just few days ago...



And, there's a few threads you might want to read, you will learn many stuff there.

Once you got the correct build of coil and mesh, HA! AWESOME taste and vape all the way to the last drop of your juice! Hope this will help and I didn't waste my times typing all this.



P/S: If still can't solve hot spot issue? Then try order FC-2000 Ceramic wick here FC-2000 Ceramic Wick 1/8th! And if you're going to order, order some for me too!
