    Abstract: A carburetor including a throttle valve for regulating the flow of air through the body of the carburetor and to an engine, with fuel being introduced into the air flow for intermixture therewith, and with the device including an air actuated element which is preferably located downstream of the throttle valve and is adapted to be displaced automatically by the air to different positions varying in correspondence with the rate of air flow through the device, and which forms a restriction varying in size with the rate of air flow and acting to enhance dispersal of the fuel within the air and assure intimate intermixture of the air and fuel for optimum functioning of the engine. The fuel may be premixed with a secondary flow of air before delivery of the fuel and secondary air as a combined stream into the primary flow of air, and the combined stream may be drawn by vacuum into the primary flow of air at the location of the restriction formed by the flow actuated member. Precise control of the amount of fuel which is fed into the primary flow is attained by automatic regulation of a valve controlling the amount of secondary air which is mixed with the fuel. A proper air-fuel ratio may be assured by utilizing movement of the air actuated element to control operation of the secondary air valve. Additional automatic controls for starting and idle purposes are actuated by a vacuum responsive element and a thermostatic element.

    Abstract: A carburetor arrangement for a manually-guided implement operated by an internal combustion engine. A carburetor supplies a fuel/air mixture to the engine, with a butterfly valve being disposed in the intake duct of the carburetor and with a choke valve being disposed upstream of the butterfly valve. A start lever is provided for actuating the carburetor in a start phase, and acts upon the choke valve. The start lever can be shifted in a direction of actuation and in an unlocking direction that is independent of the direction of actuation. The start lever can be locked in a rest position relative to the direction of actuation, and after being shifted out of the rest position in the unlocking direction is shiftable in the direction of actuation.
