I loaded up the stove friday night with my usual mix of ash and sugar maple, but I also threw in what I thought was a piece of black locust or something that looked like it. Just a normal split of it nothing huge. I popped outside for a second and wow...what a stink! Almost smelled like burning rubber! None of my neighbors stacks were going so I'm guessing it was mine. Went back in and threw in some simple pallet wood and in about 5-10minutes the stink was gone. Still wondering what that stink was!?
