A carburetor incorporating an air passage, and a fuel passage, and a rotating barrel, the rotating barrel being arranged between the air passage and the fuel passage so that a first portion of its surface is exposed to the air passage, and a second portion of its surface is exposed to the fuel passage. The rotation of the barrel transfers fuel from fuel passage to the air passage via an indent feature, the proportion of that indent feature that is exposed to the air or fuel passage being varied to meter the amount of fuel transferred. |

1. A carburetor for an internal combustion engine comprising an air passage, and a fuel passage, a rotatable barrel, the rotatable barrel being arranged between the air passage and the fuel passage so that a first portion of its surface is exposed to the air passage, and a second portion of its surface is exposed to the fuel passage, the rotation of the barrel transferring fuel from the fuel passage to the air passage via an indent feature on the surface of the barrel, fuel moving means by which the fuel within the fuel passage is caused to flow along the fuel passage and over the indent feature on the barrel, so that air brought back into the fuel passage in the indent feature is stripped from the indent feature and replaced by fresh fuel, and that the resulting air bubbles are then carried away from the region of the indent feature by the fuel flow. |
