So, at about the 18:30 mark, on the topic of how delivering fuel to the motor was developed and refined, they give us this:
Travis Taylor: Engineer and Author
"(the float) floats up and allows fuel to flow into the combustion chamber, and boom that's how you get the power."
Complete gibberish. Nobody who has the faintest understanding of how a carburetor works could write or deliver that line. It skips past "simplified", blows by "oversimplified to the point of being incorrect", and barrels headlong into "absurdly flat out wrong". The carburetor float was a stroke of genius breakthrough, but its job is nothing like this description suggests. Once you start getting the basic facts wrong, your credibility drops to zero, and any sort of educational value is lost.
I knew going in that this series was going to be weak on facts. I just didn't know how weak. But History/Learning/Discovery Channel lost any sort of serious educational value a long time ago, and have diminished themselves into a thin gruel of low standards and sensationalism. They're pretty much the video equivalent of the National Enquirer.
The historical recreations can have some entertainment value, and they mostly get the facts in the neighborhood of "right", but if you have any genuine interest in learning history or discovering things, they are not a source for anything but suggestions for topics to go learn about from a legitimate source. Wikipedia has better fact checkers.
