i am i just havent taken it out yet. sat. is the dayUnderstood, but you should be more interested in what the advance is doing in the rpm band where you're having trouble. That's why I suggested checking the timing up around 3000-3400 rpm. The reason you see the idle timing move around is due to the idle stabilization circuit that's written into the ignition control box.
