I started my smoked turkey @ 6:30 this morning. 28 f and windy. The GOSM was fighting to get up to temp, 250f. After 30 minute warm up, she was at 190. Put the turkey in and waited...and waited. Moved the GOSM closer to the house, by a corner, wrap her in a felt blanket. No help. I had also unhooked and rehooked, shook and fiddled with the gas bottle. Same 190 f. Hooked up another bottle, presto. I was hitting 250 in 5 minutes. Both bottles were filled at the same time, last week. Anyone had a similar experience with their bottles? We are holding 250 "Pops" cured bird is floating in a blue haze, internal is at 140. Merry Christmas to all. Have a safe and happy New Year.
