The quest for better fuel efficiency doesn't necessarily show a lack of common sense, but the quest for a magical, one-size-fits-all carburetor that gets 100 mpg might. There are a lot of factors that affect how efficient a particular engine is with a gallon of gasoline. Vehicle size, shape, and weight factor in. [I once heard that, aerodynamically, a Ford Pinto hatchback actually had a lower drag coefficient going backwards...not sure whether that was just a legend, or whether the wind tunnel proved it.]
And beyond the BTU's, other factors come into play. It's pretty much accepted that an air/fuel ratio is stoichiometrically optimized at 14.7 to 1...that's 14.7 parts of air to 1 part gasoline. That's with common outside air, which is about 20% oxygen. So what if we introduce more oxygen with the same amount of fuel? Well, nitrous oxide is about 36% oxygen by volume...but when introducing that high a percentage of oxygen in a normal internal combustion engine, you CAN get more heat energy from the same amount of fuel...but because you suddenly have a cutting torch effect going on in the combustion chamber, and pistons and valves tend to get melted in VERY short order. So the best compromise, in order to save engine components, is to introduce MORE FUEL with the N2O...which then negates any "potential" gains in fuel economy.
Books can be, and have been, written on the subject. But those "holy grail" carburetor stories will persist, as long as folks are willing to overlook the history of what's already been tried on the internal combustion engine.

Today's Featured Article - Converting from 6 Volt to 12 Volt - by Chris Pratt. It's a common problem for old machines especially when the weather starts to dip below 40 and the tractor isn't fired up as often. You are probably used to the 12 volt Diehard, charged with 200 amp alternator of your 3/4 ton that always is ready and always starts. It's this type of experience that brings about the many queries we get for 12-volt conversion kits. Since only a few kits are available (we sell kits for the
