Air was not able to get to the charcoal from below at all, so when the stuff on top burned and started to form a little ash the stuff on the bottom was unable to ignite. There were probably 18 - 20 unburned briquettes underneath the burned.

Got rid of the ashpan all together and raised the charcoal basket about 3/4" to make sure I'm getting good airflow. Now I only have 23-3/4" clearance between the charcoal grate & bottom cooking grate, which should be fine.

Anyway, I put another 9# bag of briquettes in the basket and poured 1/2 chimney of lit coals into the cavity in the middle. Took 3 minutes to get up to 225* and it's now coasting at 229* for about 15 minutes with one 1/2" inlet completely open and the 1/2" ball valve cracked open about 1/3 of the way.

You got it bro, just kick it once an hour to drop the ashes and she'll run there all day long!!!
