I would be curious to see what the LM-1 says? Remember that the type of manifold you have will determine what cylinders get fuel from which side of the carb. My intake is a dual plane and cyl's. 1,7,4,and 6 get fuel from one side and cyl's. 3,5,2,and 8 get fuel from the other side. This will cause your Oxgen readings to be averaged from bank to bank. a single plane is a different story. Plug color is IMO the final measure.
