Keith O - DANG, that's a sweet looking 1650. As for the carb issue, did you by any chance also add gas to the gas tank? Some of these units do have their little idiosyncrasies. They can have gas in the bottom of the fuel tank, but it's just not enough to keep the engine running. As much as I'd like to I just don't use fuel filters on these units since they can slow or block the fuel flow without a pump. To me you end up with more problems than the filter is worth. The 1650 has a screen in the bottom of the fuel tank, and other than that you may have to clean the carb once every 5-10 years.
