Carburetor and method of operating the same

A method for operating a carburetor for an internal combustion engine;

• the carburetor including:
• an intake channel;
• a throttle element pivotally mounted in said intake channel;
• a choke element pivotally mounted in said intake channel upstream of said throttle element;
• said choke element being displaceable between an operating position wherein said choke element is open and at least one start position wherein said choke element reduces the cross section of said intake channel relative to the cross section thereof in said operating position;
• a first fuel path for supplying fuel to said intake channel in dependence upon the underpressure present in said intake channel;
• and, a first valve mounted in said first fuel path for controlling the quantity of the supplied fuel;
• the method comprising the steps of:
• displacing said choke element into said one start position for starting said engine;
• providing a second fuel path defining a bypass line to said first valve;
• arranging a second valve in said second fuel path;
• and,
• actuating said second valve in dependence upon at least one operating parameter of said carburetor.
