H Towner.....you're just fine setting the piece to the side like that on that small of a cooking area....on an 18" WSM (bullet) the meat is much farther up above the fire, but here, it's right dang there.....
Here's some examples of this thinking:
Ribs down the center, two small chains of charcoal burning opposite directions....
Starting off w/ the strip of meat above a blank area or unburned coals, as the coals burn along, rotate the grate to where the ends of the piece are above the ALREADY spent charcoal / wood....that way, you're never directly above the burn...
Same general idea applies to what you did......set to the side & rotate the grate around following the burn of the chain to keep it indirect..........
Set for above (a bit more coals were added before cooking)
Them ribs came out just fine....
Same general idea for brisket...this is on a 22" so there's some more room to work....15-3/4# trimmed piece.....moving the grate around....following the burn....
Pretty big, so did have to add coals...
just fine in the end...
hope that helps some......the standard size kettle would give you more elbow room, so at least check around & see what ya can find....
