    Hi Ken,

    1. Your Johnson has a magneto type ignition system.

    2. Your ignition is not battery powered, it is a self contained magneto system. Your electric starter motor used to crank the motor over is powered by the battery. Pulling the motor over manually with a rope will also start the motor in case the battery goes dead.

    3. The way I see it, the chart says you have the correct tach. 😀

    4. Good question. I’m sure somebody else has the answer for that one.
