ok i made the gap smaller and it runs faster now but still wont idle at all. i think it has to do with the spark. the minute the bike drops RPM's the engine cuts out. once its going though it runs fairly well. it is the same as when i take the spark plug off. it takes a sec to get going, once it does it is fairly bright, but the minute i stop pedaling the spark dies even though the magneto is still spining at a speed where the spark should sustain.
