I've got a smoke hollow 4-1 with extended chimney and charcoal basket. I put 1 chimney of unlit charcoal in the basket tightly stacked on one end. I lite 12 bricquets and let them ash over then put them in one corner of my unlit charcoal, neatly stacked. Exhaust 3/4 open firebox damper oly 1/4 open, when temp reaches 200 I close damper fully. Temp will not stop climbing and within 30 minutes almost all charcoal is lit. Using kings ford blue. Any advice on how to slow it down?
