Wife just bought me a 14.5 WSM and we (me and my 9yr old son) are new to smoking we smoked a pork shoulder for pulled pork this weekend he and his sisters like it but it had a slight bitter taste. I am trying to figure out how to get more then 6 hour on a load of coals and how to remove the bitter taste. Looking to make some mods to the smoker also primarily handles on the smoking chamber.
