LH: I could hear a "Popping" in #8 carb stack at idle, almost metallic, like a valve sticking, and rough running and backfire through intake when driving. That all went away by twisting 7&8 wires or moving #8 away as far as possible.
It is an fe anomally due to firing order,as #'s 7&8 are adjacent and 8 fires right after 7.
