I recently got a new GOSM from a friend. I have done a few smokes in it and love the charcoal flavor. I previously had an electric.
I tried the minion method and the thing sky rockets to over 300*. I can do the normal charcoal method and maintain at optimum temp. I have a wok with legs inside of the original charcoal pan. I'm assuming its getting too much air and that is why the other stuff lights so quickly. I put roughly 1 chimney full in the basket and then put 3/4 of a chimney full on top of that. I tried closing the vents 98% of the way but it still does this.
I am a little confused on the vents too. My top vent is always 100%. My two side vents I always try to keep as closed as possible. To me, you want more air to come into the smoker to help cool it down but that also help fuel the fire whereas closing the vents would mean less O2 but more heat buildup.
I know there is a learning curve and Ive done a few smokes with different vent posistions and it just doesnt seem to get quite right.
