I spent way more time on this work than you might think. The magneto has been irksome since day one. It didn’t have a plate for the ignition harness. I had to procure a used one. Because it is a modification to the dual magneto accessory case… it doesn’t have an exact ignition harness you can order. So I ordered this experimental one from aircraft spruce. The instructions for attaching the ignition leads to the plate are crappy. And with the setup, not really feasible. I had to give careful consideration to how I would connect these leads, and how I would route these cables. Sniffle valve installation on the other hand was quite simple.
