OK update I'm def a carpenter but when it comes to metal work, fail lol. I bolted the kettle lid mod in place, and lit it off for a test run. I tried it with out putting cement around the few gaps I had cause it looked like the lid had a decent fit. Lit it off, and seasoned it, with the temps reaching 330 degrees. Then I started to back it off. With one ball valve, and one nipple cap off i could still not hold a temp. I was struggling to keep 200 degrees. So two thoughts come to mind. One the gap and some bolt holes in the lid is causing me to lose to much heat, or second of all I'm not building the fire correctly since I'm a newb to charcoal. I filled the basket, lit 8 coals and put it in the center, and let her go. This evening all my coals on the outside were unburned. So either i try to fix the problem, or I'm going to remove the lid mod, weld the holes shut and go to a flat lid. I'm so irritated.
