ABSTRACT:
A carburetor and fuel feed device for small internal combustion engines incorporating a pumping section which receives fuel from a supply and delivers the required amounts for the range of operation between high and low speed operation with any excess being returned to the source of supply. A control device is employed which permits deceleration from high to low speed operation without flooding by instantaneously preventing the supply of fuel for high speed operation in response to movement of the throttle valve to an idle or low speed position.
