My son gifted me with the gasket kit which he installed on my WSM. At present I have a turkey on the smoker, but can’t get the temp above 250 degrees. I filled up the charcoal ring with fresh Kingsford, added a few chunks of apple wood, put hot water in the water pan, and have all vents wide open. It won’t get above 250, but will stay around 225 degrees like this for hours on end. I was hoping to get the turkey to the 350 Range, but that ain’t happening. I may have to finish it in the oven. Any suggestions?
