Don’t modify the carburetor. Instead, build a “mixer” that fits between the air filter and the carb throat. It’s just a pipe with a venturi (a narrowing) and a needle valve to bleed in extra air.
When the next ice storm takes down power lines for a week, your generator runs on the branches that fell with the lines. When diesel hits $7 a gallon, your tractor doesn’t care. When the supply chain stutters, you look at the woodlot and see a full tank.
From the branch, a flame you cannot see. From that flame, the power to move mountains of stone. And from that power, freedom from the pump.
