Fired up the new to me reverse flow smoker and having heck getting temps to stay at 225, have even put a fan at fire box to try and help. Weather is less than idea for it today but trying it anyway. I filled my charcoal chimney up with bricks, and let them turn white before putting them in fire box, laid some pecan wood on top and let smoker heat up before I put meat in. Started another set in chimney and added it to coal bed after an hour. Fire box vent open and stack open. Any advise is appreciated. Never ran a reverse flow before, never had much problem on my standard offset.
