Abstract
A carburetor chamber cover device for covering a carburetor chamber of a portable power-driven machine such as a chain saw. The carburetor chamber accommodates an air cleaner and a carburetor for supplying air-fuel mixture to an internal combustion engine. The cover device comprises a cover adapted to close the opening of the carburetor chamber and having an aperture, and a filter plate and a blind plate adapted to be selectively attached to the cover so as to fit the aperture. The filter plate has a screen capable of arresting comparatively large particles of dust. In order to avoid troubles such as blocking of the filter plate by snow or icing of the carburetor, the filter plate is detached and the blind plate is attached instead.
