    I am still puling my hair and cannot figure out what is happening,

    Why would be the spacing (meaning diff. time period) between signals come from?

    I am very green at interpretation of the cope, will appreciate advice on these charts.
    Channel B was on the primary voltage and A channel on Secondary ignition just after the coils, before distributor
