Abstract
To allow an intake negative pressure to directly act on a fuel outlet formed on a nozzle tube, and to guide a fuel discharged from the fuel outlet in the nozzle tube to the fuel-air mixture passage. A rotary carburetor () has a guide plate member () downstream of a fuel outlet () located in a through-hole (). The guide plate member () has both side edges () away from an inner wall surface () of the through-hole (). The through-hole () is divided by the guide plate member () into a first passage portion () and a second passage portion (). The first passage portion () communicates through a piston groove with a scavenging passage of a cylinder. The fuel discharged from the fuel outlet () is guided by the guide plate member () to the second passage portion () and is supplied through the second passage portion () to a fuel-air mixture passage () of an engine intake system.
