anyone know what might have causes a sooty, foul smelling wood burn for me? I cut a limb from a live citrus orange tree. The diameter was 4 inches and 1-1.5 inches thick, and the wood had dried for several months. When i used it for smoke wood in the weber, the smoke ended up getting dark, sooty and had a bad odor. I am reluctant to try it again even though i had a few successful burns with similar pieces but if i wasn't there, it could have ruined my meat
