Hello everyone, I am very new to the whole forum thing so forgive me if this subject has already been addressed. I currently own a grill very similar to the "Brinkmann Single Zone Charcoal Grill." The main difference is that my grill does not have the rivits in the lid for a rotisserie attachment. I have been looking online alot about smoking and i think i am ready to start doing it. I have attempted to smoke a brisket a few times and though they were not horrible they were not as fall apart tender as i wanted them to be. After much more research i have a new technique but the problem is i have trouble maintaining the heat on my grill. The last few times i tried to smoke i noticed alot of smoke leaking from around the lid of my grill. Do i need to make the grill air tight so only the air vents allow entry and exit of air and smoke? or is it fine the way it is? Also if i do need to make it air tight what would be best to use to plug these leaks?
