Yup. That's it. I have done the same mod.'s too except the felt tape - mine doesn't leak too bad. The only thing I can figure is last time I used it I used hardwood charcoal and from what I am hearing that raises your heat. So, this time I am going to try the regular Kingsford blue and white bag charcoal. I think I will go through more of it, but hopefully at a lower overall temp. I also did use the "minion" method - but there I think I over filled it - again with the hardwood charcoal. Any idea on a "briquette" count? My brother has a WSM and his book said 100+ briquettes for his....holy cow that seems like a lot.
So far here's what I've got:
1.5 hrs. per lb. ( 7.67 lbs x 1.5= 11.5 hrs. ballpark )
smoke at 225-250 deg.
@ 140 deg internal butt is done, take it to 180 for pulled or 190-200 for sliced
