Abstract
A fuel feed device for an internal combustion engine including a main fuel system including a charge forming device that supplies fuel, air requirements to the engine for most running conditions. An automatically operated auxiliary supply system is provided for supplying additional fuel and, in some instances, air to the engine in response to specific running conditions such as cold starting or cold enrichment. This system includes an automatically operated valve for controlling the fuel discharge. A manual override valve is provided that will permit manual selection of fuel enrichment or will shut off the fuel enrichment regardless of the condition of the automatic valve.
