Hi there.  Finally pulled the trigger and got started BBQing.  Only....  I need a little coaching.  Should I see smoke for the entire cook time?  I've been smoking a brisket for 4 hours now.  The smoke seems to stop after about 2 hours.  It starts up again when I add/stir the coals.  I've checked and I still have wood in the chamber.  Thanks!
