After my unexpected success lighting the Egg from the bottom vent while trying to unfreeze a stuck Egg, decided to try again tonight for a pizza cook. Stirred the used lump and added more to fill the firebox. Cleaned out most of the ash, and used 3 oil soaked paper towels burning in the bottom vent. After about 15 minutes, I had flames coming out of the top of the Egg. This was at 400 degrees dome (calibrated probe) with plate setter legs up, grid, raised grid, pizza stone. With all the hardware in the Egg, still had flames coming out the top. No Daisy wheel, bottom vent open about an inch and a half. Closed bottom vent to about an inch, flames stopped and settled in at 500. Amazed at how fast it came up to temp.
It's not a science, it's an art. And it's flawed.
