I used to live on a lake with a large carp population. I took a burlap bag, filled it 1/2 way with shelled field corn and a couple rocks. Then sank it a comfortable casting distance, after a few weeks the carp would come to the bag to suck the rotting corn through the bag. I fished close to the bag with open face spinning outfit, about 6# test line, and small treble hook only, no weight or leader. Form a Wheaty “Breakfast of Champions” ball around treble hook just big enough to cover barbs, very gently cast to bag and leave bail open so there is no resistance. When you see line going out, let a few feet go out the set the hook and get ready for a fight. Wheaty ball is made by taking a handful and dunking it in water then forming around hook and pressing firm. Casting requires smooth action with no jerks or excessive force. When they are biting you can catch a mess fast.
