Abstract
A diaphragm type carburetor comprising a main body portion defining a venturi having an air intake side and an engine outlet side. The carburetor has a throttle shutter mounted within the venturi between the air intake side and the engine outlet side, and a metering chamber supplies fuel into the venturi via a main discharge port. The main discharge port opens into the venturi on the air intake side of the throttle shutter. A monitoring means (FIG. 3) is provided to monitor an engine parameter and an electrically controlled valve means is provided to adjust the fuel flow through the main discharge port into the venturi. The valve means is responsive to an electrical signal generated by the monitoring means in response to the engine parameter.
