Monday around noon, i fired up UDS for some MOINK balls and 3 fatties. After they were done i shut it down( or so i thought-alcohol involved of course). When i got home yesterday (Wednesday)i told myself " wonder who's cooking" as i could smell the sweet aroma of smoke. As soon as i walked in the house my neighbor called and wanted to borrow my battery charger. Well i walked out to my shop behind the house and found out i was the one cooking. :laugh: I had not closed the ball valve completely and the daisy wheel exhaust was also partly open :doh: Temp was @ 125. I figure i got at least 54 hours of burn time on a full basket of charcoal and it was still going.
