I am also having this problem. Did you ever figure out what was causing it? I figure something in my valves is awry, I'm going to get it tuned up whenever is next convenient for me, but for now I just adjusted the idle screw so the thing idles higher and doesn't cut out when I come to a stop sign... Obnoxious, but drivable
