A starting mechanism is provided for an internal combustion engine, and includes a diaphragm carburetor. A butterfly valve is disposed in the intake channel of the carburetor and has a pivot range into which at least one fuel nozzle opens. A starter valve is disposed in the intake channel upstream of a Venturi section thereof. A by-pass conduit is provided for additional air supply when the starter valve is closed, and branches off upstream thereof and opens out into a fuel/air mixture path downstream thereof. The control element determines the rate of air flow in the by-pass conduit, and is adjusted by a temperature sensor that is disposed directly on the internal combustion engine.
