you can also get the honda gxh50 http://www.trupower.com/honda/gxh50.htm it's a 50cc over head cam 2.5 hp gas engine, it uses 250 grams of fuel per HP per hour, so at full speed/power a gallon of fuel would run it for over 5 hours.
http://www.trupower.com/honda/honda-4s-engines.htm has the 22cc and the 31cc modles as well, and all the specs, tourqe curves, fuel useage, and all that other stuff listed.
