This may be among the simplest methods for carp fishing that we've used, but it's also among the most successful. We have caught 5 commons in a single evening session using just this method. We just use a small bobber (small bobbers will go under with less resistance so the smaller the better) placed roughly 6 feet above the hook, with a few small split-shot sinkers placed right under the bobber. The reasons for the sinkers are 1. to aid in casting and 2. to aid in the bobber going under with less resistance, since carp typically don't hit hard. Still, most of the time your only indication will be the bobber running. The point of this rig is to present the hookbait (we prefer bread for this rig) right over the bottom, so adjust the bobber position to fit the water depth you're fishing. This rig works best in creeks and small rivers with little to no current and max depths around 6ft-8ft. This is our go-to rig when fishing creeks, bayous and other shallow waters with high carp populations.
