Abstract
A fuel supply system for a small engine including a constant level fuel chamber for receiving fuel from a fuel tank through a fuel drawing pipe to eject the fuel into a carburetor through a main nozzle after temporarily storing the fuel therein. A cover is provided to enclose the fuel drawing pipe and the constant level fuel chamber to separate the fuel drawing pipe and the constant level fuel chamber from a fuel storing section in the fuel tank, to enable fuel of a constant flow rate to be fed to the carburetor through the main nozzle irrespective of variations in the liquid level in the fuel storing section.
