Magneto coil

[ILENGINE]

May not be relative but several years ago was working on a Briggs twin replacing ignition modules, and Briggs had changed the style of module, this was pre CDI Briggs modules, but you had to grind the aluminum block between the two post that secured the module, because the coil pack would hit the block.

I remember that now, created some interesting results, but I’ve forgotten which modules.
