Hey all - we picked up the new 40" Bluetooth model yesterday to replace a defective 30" we had sent back. I smoked some chicken wings last night @250 for 1.5hrs with mesquite the entire time. Same as I did in the first smoker without issue. But last night when I went to add some more chips towards the end, it started producing a nasty smelling thick yellow smoke. I pulled them out fast and luckily they were already done. I had perfect TBS when I first started them. This had happened once with the first smoker when I did some bacon wrapped dogs so I'm sure it's something I'm doing wrong. Planning on doing some baby backs tonight and will be picking up an amazen soon. I don't want this to happen during a much longer smoke and ruin my ribs. Any ideas what's going on when I add more chips?
