As far as the Maverick guy goes. The A/F ratio the vacuum inch/hg and the cars Cd tells the story. Put these values into an engine sim and things look a little weird?
The thing that drives me crazy about crazy claims without making big changes to the engine is well the engine. Each engine has a BSFC and BSAC fingerprint.
You can change the fuel to vapor put a smaller then normal carb on it but the facts are you did nothing to improve on the engine BSFC numbers. The ICE is the biggest problem. You can only squeeze so much out of it.

I'm not doubting that the lawn mower carb did better then his other one. Major gains can be made from one carb to another. The fuel test he did didn't sit well with me. I even showed a friend the same test in my 97 stock eclipse. Doing the same test "short fill" my cars fuel mileage went up from 30mpg to 65mpg. The Maverick guy was always about getting more hits and subscribers and man did it pay off for him. Hope he sleeps well at night.
