Trying to cool down my temp in my Char-Griller duo combo and having a tough time! It's steady at 275 and I've closed all the air flow vents. Trying to smoke a 8.5lb brisket and a 6.5lb brisket and would like to drop the temp down to 220.
Should I shovel out a heap or two of coal??
Thanks for any tips or advice,
