    Now that I'm home from a stressful day I can't imagine why I ever cared whether people believe in magic numbers or not. Nobody is interested in what I'm saying so I'm just wasting space.

    Not quite sure what the fuss is with the magic number the instructions clearly say rev the engine until the timing stops advancing, this is where to set the timing.

    Those are instructions for the Micro Digital System. I have the Micro Power Ignition system. It's instructions can be found here http://www.boyerbransden.com/pdf/KIT00303__BOX00210_.pdf

    I get the weight and horsepower from this link http://www.clink.net/Kevin/specs.htm
    Wikipedia states it's weight at 450

    Let me put it this way and you should be able to come to an understanding of the system. Full advance can be set at various RPM's. Using a digital tachometer which works by counting firing off of a spark plug wire I could run the engine at precisely 3000 RPM then move the stator plate so that the marking on the rotor just comes up to align with the 40 degree BTDC mark on the stator. In fact it won't move past it. I could also run the engine at precisely 4000 RPM and move the stator plate so the marking on the rotor just comes up to align with the 40 degree BTDC mark on the stator. And of course I am using a strobe light to view this

    Gee, I'm glad you explained all that; I've only been installing Boyer ignitions since 1994. As far as timing drill goes, the MP and the MD are the same.
