Read somewhere that heat is best controlled by leaving stack full open and regulating door on fire box. Using this method I have trouble I have trouble with consistent with internal temp. I have two Gage's on my Oklahoma Joe. One at the top at the far end from the fire box; and the other at grate level between the fire box. Last time I used it, I adjusted both the door and the stack; and was able to maintain an even 225 deg. Problem was very little smoke flavor. I've seen some u-tubes where the smoke outlet was modified to mid smoke chamber level. Any suggestions?
