    The lures of better performance, more efficiency and less trouble got to me.
    I broke down and got a pertronix system for my 2.25. The install was a breeze
    (after realizing the + - leads were reversed on the coil) and it instantly
    sounded much better at idle. My dizzy shaft has a bit of wobble which must
    not matter much to a magnet & hall sensor. Also idle vacuum went from 19-20
    up to 21-22.

    Problems have arisen though. As hard as I try to set the timing by ear, it
    just won't go. I turn the dizzy a little bit and it starts pre-igniting, turn
    it the other way and there is major loss of power. It settled at an un-happy
    medium where it only pings with my foot all the way down (WOT), and the power
    loss isn't so terrible. With points, it would cruise at 65, now it won't
    break 55. Should I try messing with the little knurled knob on the vacuum
    advance? I've fiddled with it in the past (w/points) and never noticed much
    difference. Is my dizzy shot? Cap and rotor are new, wires and coil 2 months
    old, plugs gapped and looking good.

    Any ideas from the esteemed list?
    Casey
