Update on progress:
Got it leveled out to around 225 before going to bed last night, and this morning, woke up to find it chugging along at 180- not bad! A shake of the drum to settle some ash and a tiny bump of the valve had it back up to 225 in a few mins. Best of all, barely any of the coal has been burned! I'm going to let it go all day while I'm at work and see how it is this evening. Thanks again everyone.
One more thing- there was about 1/4 inch of water in the bottom of the drum after running all night, I'm assuming it's condensation from the intake of our very humid coastal air?
