Re: ignition fix

You can also put the original bad coils back in, assuming the primaries are OK. Cut off the secondary coils first. Run one wire to ground, run the other out out the bottom of the mag plate. Also, run a wire from the points out the bottom of the mag plate. Then mount OMC coils somewhere under the cover, on the block. Connect one OMC wire to the wires coming from the primaries of the B-S coils. Connect the other to the wire coming from the points. This basically puts the primary of the OMC coil in series with the primary of the B-S coil. Run secondary wire to the secondary of the OMC coil to the plug.

This allows you to maintain magneto ignition, you don’t need to carry a battery.

I did this with a Merc 5 hp, and it ran fine.
