Abstract
A start-fuel supply device in an internal combustion engine for a portable equipment comprising a start-fuel primer pump rotatively coupled to a starter motor of the engine, a fuel metering device for receiving a charge of fuel from a metering chamber of a carburetor during the reverse rotation of the start-fuel primer pump, and a fuel nozzle for injecting fuel from the fuel metering device to an air intake passage of the carburetor during the normal rotation of the fuel-start primer pump. A passage portion between the fuel metering device and the start-fuel primer pump is connected to a fuel reservoir through a by-pass passage provided with a check valve which allows a flow from the fuel metering device to the fuel reservoir.
