    You see why Im pretty confused now lol... This is why Im thinking its electrical since it keeps producing the same symptoms with different carbs and jets. I just foot have a cdi box or stator to swap and try.

    So I got a replacement stator but it still hasnt fixed the problem. Anyone have a CDI box? Thats the only other thing besides coil or the jetting is completly off the chart. Anyone got any ideas now?

    Im baffled.... I have changed carbs, stator, CDI, kill switch, jetting, fuel pump, spark plugs.... It still wont rev all the way out on top. Runs great just revving it but if you hold it wide open it will cut out..... Anyone else got an idea???
