40MPG V8 Lawn Mower Carb vs. 1974 Ford 302 [video]

  I found this interesting and wanted to share with other tech enthusiasts that might own older vehicles that wish to go green(ish) with their existing pre-smog vehicles. TL;DW A person took an old Ford and 3D printed a controller enclosure to manage the airflow in a lawn mower carburetor to achieve 40MPG in a vehicle that is arguably sub-optimal for this test.

  It doesn’t ever sound like it goes into full WOT. Is this just for MPG or does it have the range to actually provide airflow and fuel for peak HP for that motor as well? Note: did not watch full video.

    He hits 75-80 on the highway in this 4 speed but never opens it up all the way and never tries to light it up on the streets. I too am curious but maybe he shows that in another video. I will poke around and see if he did anything more with it.

  Many years back, Popular Mechanics (or one of those similar magazines) had an article about a 100mpg carbeurator. My grandfather had a shop, so he built one. It worked, but if he tried to "gun it" or was travelling too fast (which incidentally wasn't very fast at all) it would stall, and take some effort to restart. I don't remember much about it since I was a kid at the time, but was basically a box that collected gas fumes, instead of using the venturi effect with air and "wet" gasoline alone.
