    Interesting. Maybe I’ll put a runout gauge on the flywheel to see if there’s any wobble on the shaft.

    But I suspect, as has been confirmed here, the Sierra coils are the issue. And if the radius on the ends of the lams are wrong, moving these inboard a tad (by enlarging the holes) seems like a non-solution.

    Looks like I need to get some OMC coils on order!
