Let me understand.. you want to trade a solid state dang near bullet proof = ignition system for something that has less energy and requires regular ove= rhaul and servicing?

Unless you are installing in a high wing, gravity fed will be a non-starter= (even as a back up).

You would be better served with a dual battery redundant electrical system.= Some folks are even running permanent magnet generators. If you lose an al= ternator/charging source, you can shed dang near all your load, and have ov= er an hour flying time to get on the ground..

Chris's plane has dual battery, independent busses, and dual alternator= s. That setup is less failure prone than a mechanical device that WILL requ= ire overhaul or replacement every 500 hours or so.

To answer your question, I dont know of ANYONE running mags on any auto con= version engines at all. Just lawnmowers and lycomings/continentals/franklin= s.
