Jeff,
Contrary to your informative articles, the test can be set up to show a power / driving difference, or not, without jockeying timing. The people writing the articles almost know what they are talking about.
The missing link here is the fuel density. Auto fuels are getting less dense. It even changes among brands. Think what this does to a float setting.
Aircraft Airframe and Powerplant technicians have been on top of this now for awhile. Airplanes are a place where the technology is further behind than Cobras. A guy buys fuel for his plane from one place and the engine misses and hicups, and buys another brand and all is well. They check the float setting and it is within parameters. Usually barely though.
There is no reason why a guy in a cobra could change fuel and not notice a difference in how it runs. It doesn't have to be his "imagination".
