Ugh, that was the most frustrating build of my life!
Apparently Kebo saw fit to assemble the deck themselves, unlike with my v1. Thinking that they knew what they were doing, I built coil after shorting coil, only to find out they hadn't assembled the center pin correctly, so I was loosening the post instead of just the contact screw.
As for the draw, there's a slight whistle, but it's actually a little less than my v1. I keep a fairly light draw, so it might go away if I were to tighten it up more.
