I'm about 1 1/2 hours into my second smoke ever, this one is a 8 1/2 lb pork shoulder. I'm using the ECB and just today made the mods suggested: holes in coal pan w/vent, holes on lid w/vent and moved the legs to the outside. I did the rub last night and brought it up to temp before starting the smoke. I filled the water pan with boiling water, filled the pan with lump charcoal and put a few hot coals on top. It came up to about 200 but has been hovering around there since. Any ideas what's going on? The temp has been steady, which is better than my first smoke when they were up, down, up, down, etc. How can I get them a few degrees higher?
