My son picked up a CZ Jawa moped on cl for 100.00. Its in pretty good shape but not running well, dies out. Took the carb apart and cleaned it. The main jet was pretty clogged. As dusk approached, we hit a snag assembling the carb slider to the cable. Its one if those gurtner type deals, where youre best off starting with a fresh long length of cable to feed through the domino throttle. Not sure yet on the hp rating, but the funky carb measures 12mm. We'll see tonight, if it rips!
