As ss55 indicated there was a class-action lawsuit brought against engine manufacturers for over-stating their engine's power output. From what I understand the ratings were being taken at engine speeds that were not attainable in the real world, primarily because blade tip speed regulations limited the maximum engine speed to around 3000 rpm for walk-behind mowers. The old power ratings were generally taken at 3600 rpm. My thinking is that the companies didn't want to lose face by de-rating their engines to account for the reduced speed so Briggs and others started rating the "power" using torque instead. This is actually quite silly since torque is not a unit of power at all and it tells you nothing about the work capacity of an engine until it is combined with the rotational speed at which it is being delivered. The propaganda video that Briggs has out on YouTube trying convince us that torque is such a good "power" rating is really laughable.
