    You need to get the two working together, the draft between them is the key

    Ideally, chimney/exhaust should be wide open and air flow/temperature should be controlled by the metering the intake.

    Use this to figure out your metrics for airflow....

    Here’s your quick fix. Find a 1/4” to 1/3” stick laying around. Use it as a shim when you shut the grill lid. Works like a charm for me. Make sure your exit stove pipe is wide open, and if your vent cover at the exit isn’t big enough to allow the smoke to exit fast enough, get a bigger one. Not sure how much wood you are burning, but coals shouldn’t be choking you down. Anyway, the stick trick should help.

    (Edit) you obviously don’t want your exit pipe wide open throughout the cooking process, just while you are dealing with periods of heavy smoke. Otherwise you will be running the temps up too high.
