The problem with the exaust analizer is they are generally set on 14.7:1. This is a rich setting for cruise and a lean setting for power. 14.7 is standard because any hotter and the nitros oxide emissions get worse due to the increase in heat.
Everyone always states that back in 19xx they developed a carb that got 10000mpg. Well, the EPA emision standard pretty much require a mixture richer then what cars are capable of running on. Limmiting cars to a rich mixture as they do limits the advancement in lean running engines.
