1. A generator comprising:
an internal combustion engine comprising:
an engine block including a cylinder comprising a piston;
a crankshaft coupled to the engine block and configured to rotate about a crankshaft axis in response to movement by the piston; and
a spark plug configured to periodically generate a spark to ignite fuel in the cylinder to control the movement of the piston;
an alternator comprising a rotor and a stator, the rotor configured to rotate with the rotation of the crankshaft to generate alternating current electrical power;
a controller configured to control a rate of fuel supply to the internal combustion engine;
a first fuel supply configured to supply a first type of fuel to the cylinder;
a second fuel supply configured to supply a second type of fuel to the cylinder; and
a switch configured to selectively enable the flow of the first type of fuel from the first fuel supply into the cylinder and disable the flow of the second type of fuel from the second fuel supply, wherein the switch is communicatively coupled to the controller and wherein the controller is configured to receive an indication of a fuel type based on a position of the switch.
