An internal combustion engine carburetion system comprising:a frame having two air flow channels; two throttle shaft assemblies connected to the frame and extending into respective ones of the air flow channels; and a movement system for moving the two throttle shaft assemblies, the movement system being adapted to rotate both of the throttle shaft assembles at a same time for a majority of angular rotations of the two throttle shaft assemblies wherein ends of the two throttle shaft assemblies are directly connected to each other by a connection at the ends.
- 8. An internal combustion engine carburetion system comprising:a frame having two air flow channels; two throttle shaft assemblies connected to the frame and extending into respective ones of the air flow channels; and a movement system for moving the two throttle shaft assemblies, wherein the frame comprises at least two frame pieces, each of the frame pieces having a respective one of the air flow channels therein, and wherein the two frame pieces form a fuel metering chamber therebetween.
- 9. An internal combustion engine carburetion system comprising:a frame having two air flow channels; two throttle shaft assemblies connected to the frame and extending into respective ones of the air flow channels; and a movement system for moving the two throttle shaft assemblies, the movement system being adapted to rotate both of the throttle shaft assembles at a same time for a majority of angular rotations of the two throttle shaft assemblies, wherein the frame comprises at least two frame pieces, each of the frame pieces having a respective one of the air flow channels therein, and wherein a second one of the frame pieces has a fitting at a side of the first frame piece, the fitting having a conduit therethrough connected with a second one of the air flow channels.
- 10. An internal combustion engine carburetion system comprising:a frame having two air flow channels; two throttle shaft assemblies connected to the frame and extending into respective ones of the air flow channels; and a movement system for moving the two throttle shaft assemblies, the movement system being adapted to rotate both of the throttle shaft assembles at a same time for a majority of angular rotations of the two throttle shaft assemblies, wherein the movement system comprises two drives for respectively moving the two throttle shaft assemblies.
- 11. A carburetion system as in claim 10 wherein a second one of the drives moves a second one of the throttle shaft assemblies at least partially based upon engine speed or engine load produced by position of a first one of the throttle shaft assemblies.
- 12. An internal combustion engine carburetion system comprising:a frame having two air flow channels; two throttle shaft assemblies connected to the frame and extending into respective ones of the air flow channels; and a movement system for moving the two throttle shaft assemblies, the movement system being adapted to rotate both of the throttle shaft assembles at a same time for a majority of angular rotations of the two throttle shaft assemblies, wherein the movement system comprises a computer controller for moving the two throttle shaft assemblies in predetermined positions or rotations relative to each other.
- 13. An internal combustion engine carburetion system comprising:a frame having two air flow channels; two throttle shaft assemblies connected to the frame and extending into respective ones of the air flow channels; a movement system for moving the two throttle shaft assemblies, the movement system being adapted to rotate both of the throttle shaft assembles at a same time for a majority of angular rotations of the two throttle shaft assemblies; wherein the movement system comprises a controller for moving the two throttle shaft assemblies in predetermined positions or rotations relative to each other, and a sensor connected to the controller for sensing a predetermined characteristic of an engine or device the engine is attached to.
- 14. A method of assembling a carburetor for an internal combustion engine comprising steps of:providing a frame having two air flow channels through the frame, the frame having a fuel conduit system for supplying fuel to the two air flow channels; connecting two control shaft assemblies to the frame, a first one of the shaft assemblies extending into a first one of the air flow channels; and operably connecting the two control shaft assemblies to each other to coordinate movement of a second one of the shaft assemblies at least partially relative to movement of the first shaft assembly, wherein movement of the second shaft assembly at least partially controls supply of fuel delivery to a second one of the air flow channels, and wherein movement of the first shaft assembly from a first idle position to a second wide open throttle position has a coordinated movement of the second shaft assembly for a majority of angular rotation of the first and second shaft assemblies from a first small or no fuel supply delivery position into the second air flow channel to a second relatively larger fuel supply delivery position with fuel delivery from the fuel conduit system being switched, at least partially, from the first air flow channel to the second air flow channel by changes in vacuum pull in the first and second air flow channels when the two control shafts are moved between their respective first and second positions.
- 15. A method as in claim 14 wherein the step of providing the frame comprises attaching a first frame piece having the first air flow channel to a second frame piece having the second air flow channel.
- 16. A method as in claim 14 wherein the step of operably connecting the two control shaft assemblies to each other comprises rotatably connecting two ends of the control shaft assemblies to each other.
