What does carburetted mean?
Carburetted is an adjective meaning charged or enriched with carbon or, more precisely, with volatile hydrocarbons. It appears most often in two technical contexts: historical gas manufacturing, where "carburetted water gas" described steam-derived gas boosted with hydrocarbon vapors to burn brightly as an illuminant, and automotive engineering, where a carburetted mixture is one in which air has been charged with fuel vapor by a carburettor before entering the engine's cylinders. The word carries a distinctly technical, old-fashioned register; it belongs to the vocabulary of Victorian gasworks manuals and classic-car workshops rather than everyday speech. American English typically spells it "carbureted" with one t, while British English doubles the consonant. Though rarely heard outside specialist circles, it survives in engineering literature and offers a window onto an era when town gas was literally manufactured, gallon by gallon, by enriching simple gases with hydrocarbons.
Charged or mixed with a hydrocarbon; describing either a gas (especially carburetted hydrogen) or a fuel–air mixture enriched with fuel vapor.
"The plant piped carburetted gas to every streetlamp in the district."
Technical register; largely historical except in discussions of older engines.
Past tense and past participle of "carburet": to combine, mix, or charge (a gas or substance) with carbon or a volatile hydrocarbon.
"The engineers carburetted the water gas with petroleum vapors to improve its luminosity."
Before electric lighting took over, city streets glowed with "carburetted water gas" — ordinary steam doctored with hydrocarbons to make it burn bright.

Etymology of carburetted
Carburetted derives from the verb "carburet," itself formed from "carbon" — ultimately from Latin carbo, meaning charcoal — combined with a French verbal ending. The term entered English in the late eighteenth or early nineteenth century through French chemistry, at a time when scientists were systematically classifying compounds involving carbon. Its cousin "carburettor" (the device that mixes fuel vapor with air) shares the same root, as do "carbonate," "carbide," and "carbohydrate." The double-t spelling reflects British convention, while American usage simplified it to "carbureted."

How carburetted is actually used
Chiefly technical and somewhat dated; found mostly in historical accounts of gas manufacture and in discussions of older internal-combustion engines. The spelling "carbureted" (single t) is standard in American English, while "carburetted" is the usual British form.
Easily confused with carburetted
"Carburized" refers specifically to hardening steel by infusing carbon into its surface in metallurgy, whereas "carburetted" describes gases or fuel mixtures enriched with hydrocarbons.
