For a better pellet burn I suggest raising the flame above the intake with some kind of screen, and make sure you have room for ash to fall below that level. I also like the air being blown from the top into the cooker with the air pump. 86 the wood chips, just to ruff for what you are doing. In order to keep ash from blocking airflow you may need to give the side a rap or two now and then, to let ash drop away. Also suggest not filling it to much and adding if need be.
