Hi all, I have been smoking with my masterbuilt Dual fuel using propane since October with great success. No mods other than the Cast iron skillet. Use chunks only. Problem I have been having is that when I do any smokes at the 225-250 range, the chunks just don't smoke. Propane knob is at medium and Lower to achieve these temps. My guess is that the propane flame not being large/ hot enough is not heating the cast iron skillet hot enough to start the chunks smoking. I have no issues getting smoke when I cook butts which are usually around 300 degrees for me. Anyone experience this in hot weather? It's in the 80s and sunny here. In the winter I suspect I ha no problem because the ambient temperature caused me to have a high flame on the propane burner. Thanks in advance for your help.
