The snake method is my go-to method for ribs on the kettle.
I like to put some foil over the areas of charcoal that will have drippings on them.
Light 15-20 briquettes, then load-up the grate with racks of rib goodness.
On a one-touch, I keep the intakes at a quarter to a third open.
On a 3-wheeler, I keep two intakes closed, one fully open.
About every hour or so, I lightly touch the bowl to find out where the "burn" is.
Then rotate the lid so the vent is opposite the burn. Lid vent is always fully open. YMMV
Takes about 4.5 to 6 hours using this method. Ribs turn out fantastic!
