I have read various articles about Vent position and or air flow for the MES cookers. I was hoping to bring that all into 1 thread. It seems if I am using wood chips, everyone seems to agree that you leave the vent wide open to ensure smoking and close it when you just want heat. Now the question I have is has anyone modified the Vent to improve airflow? I have seen some threads about installing a simple elbow from Hardware store, attached to the vent opening and this can help improve airflow?? Not sure how adding an elbow helps airflow but I am curious if anyone here has experience with modifying their MES to improve it?
