If you still have water in your water pan that's a big part of the reason why the temp isn't increasing. The meat is also a heat sink. Remember, there's a LOT of water in meat. Once the water pan boils dry you'll see the temp increase unless you used up too much fuel heating the water and the meat when it is friggin' cold outside. The cold is sucking a lot of heat out of your uninsulated WSM. You can always fire up more charcoal in a chimney, ash it over then use the door as a coal chute to add the hot coals to the fire. Then reach in with long tongs to spread the coals around.
Sooo weird issue. I'm maintaining about 225-228 but it's not going above that.. I have all my vents open wide... I used the modified minion method... anybody know why? is it because I have 16 lb's of meat on there??
How long until you want to eat? If you have another 4 or 5 hours, let it go. If you want to eat in 3 to 4, wrap it.
So we're 17 1/2 hours in so far... pork temp is at 176... it was 180 but now it's down to 176... i had to add more charcoal..
Think I should just let it keep going or wrap it in foil?
