    OK johnnyrude, after much study (again), I think I have the problem figured out. I have been making those timing fixtures for over 3 years, and nobody has complained. Now you come along and say it is 180 degrees out. You may be right.

    Picture from the service manual shows #2 points to be on the left (that would be #1 if it were the Universal Magneto).

    Wiring diagram in manual has front of motor at right side instead of top of page. Infers that the upper coil is #1 (WRONG)

    Rotating wiring diagram to put front at top changes position of coils. Upper one is #1 (correct).

    So, what’s wrong with the timing fixture? They changed the position of #1 and #2 points (swapped left to right). So, timing fixtures are stamped with T & B ends swapped to match. HOWEVER, I now see that OMC milled the crankshaft key slot 180 degrees from the old position, which puts T & B back where they used to be.

    johnnyrude, I am going to sent you a corrected timing fixture. Please let me know how it works out
