Hello everyone! I am fixing to smoke ribs for the first time this Sunday for the big game. I have a Char-Broil Gas Smoker like this one http://www.charbroil.com/consumer/pr...10&Name=Series. I need to know how to control the damper on the top. I want to make sure that I don't ruin the ribs by them getting "smoked out" and tasting bitter from all the smoke. So my question is do I leave the damper closed or do I open it a certain amount? Thanks in advance!
