1. A dual fuel generator comprising:
an internal combustion engine couplable to a first fuel source and a second fuel source to selectively receive fuel therefrom; and
a fuel selector configured to control a flow of fuel to the internal combustion engine, the fuel selector comprising:
a selector plate;
a first fuel valve assembly positioned adjacent to the selector plate and including a first fuel valve and a first fuel valve handle, the first fuel valve handle being actuatable between an ON position and an OFF position to selectively open and close the first fuel valve;
a second fuel valve assembly positioned adjacent to the selector plate and including a second fuel valve and a second fuel valve handle, the second fuel valve handle being actuatable between an ON position and an OFF position to selectively open and close the second fuel valve;
a selector switch slidably coupled to the selector plate so as to be movable between:
a first position in which the selector switch covers the second fuel valve handle so as to prevent actuation of the second valve handle to the ON position; and
a second position in which the selector switch covers the first valve handle so as to prevent actuation of the first valve handle to the ON position; and
a carburetor fuel shutoff solenoid that is activated when the selector switch is in the first position.
