My buddy that just installed the buck 91 found a lady that was moving to a nursing home that was selling 3 cords of mixed wood. She said her husband split and stacked the wood 3 years ago before he passed away. Well we got it home and started burning it and all its doing is turning black and not putting off much heat. The coals are really big and dont want to break up. To get it to burn he has to turn up the stove alot even then most of the coals wont turn to ash. And when you take the coals out they stink bad. Does anyone know what kind of wood this could be? I dont have pic but it has a red tint to it, stringy and is heavy. Does that sound like red elm? I've never burned anything like this so i dont know. Half of it is this wood, now the other stuff is burning great. Thanks, JD
