So I got my Kingtu over the weekend, was ordered off eBay before all the listings got taken down (someones really cracking down on them

). It actually looks pretty darn good, I'm actually kind of impressed with the build quality of everything. I haven't built it yet, but so far I looked through some of the common problems and I don't seem to be having any of them. Tank didn't seem to leak, my post screws FIT (sheesh, how did they mess that up?), the deck came out and the W deck fit in no problem, the AFC ring feels smooth and amazing, airflow seems to be flowing just fine, no rust, etc. I guess I won't really be able to test the 510 having any issues or shorting until I build it, which I am going to do tonight.
One thing though, how tight does your decks fit into the chimney? My decks seem to fit kind of snug, not like I have to force it, but the deck and chimney definitely make contact with each other. I'm concerned that might lead to scratching the inside of the chimney and eventually removing the coating, after screwing and unscrewing lots of times.
