One thing you could do that's not too expensive is to fire up the drum with a full load of coal, just like you were going to cook something, and set the temp where you want to run. By doing this you can see what adjustment you need to make and how long it takes for an adjustment to affect the way the drum is running. You can also have something cool to drink, Ice tea, lemonade, you get the idea, while learning what kind of an attitude your drum has. Could also have some brats and or burgers ready to go on later to show you what it does to open the lid and let it get a breath of air. Just thinking of things that could possibly help you without costing a fortune.
