    Exactly what am I looking for?
    I TNT’d last Friday and drove it home, haven’t restarted it since being put back in the garage.
    This is with 93 pump premium and 110 in the tank.

    Running pretty lean. And from the line on the ground strap, maybe a little too much timing

    You looking at the slight dark area between the darker top of the ground electrode and the lighter bottom?
