Prof - There have been several posts on other threads that the only difference between the regular and CARB eu2000i is the gas cap.
DSchmidt - Those engine features you pointed out are troubling to me. Had I known about them before I bought the eu2000i, it may have scared me away. Talking about the "camshaft" is even an overstatement because it's just a single lobe on the side of the belt sprocket. On the other hand, these are traits of the gx100 engine, and there are zillions of them out there that seem to keep running. I'm always cautious with new technology that appears cheap and/or flimsy. Sometimes I'm right, and sometimes it's a learning experience.
