Am doing condition inspection and have had to replace the start ring on fly wheel due to 4 broken gear cogs.
The issue is kick back from electronic ignition on start. In talking with Robert Paisley, this is happening because I do not have back up 12 volts for the system. Voltage drops during start and EI looses its brain and fires way off schedule.
I stopped using EI for start some time ago when this happened repeatedly. It does not happen starting with left impulse coupled mag. I have mag hooked up to top plugs so it starts very easily. When engine is running smoothly, turn on EI. No big deal.
It is not a starter issue, am using Sky-Tec NL unit, it spins engine very nicely and its gear cogs are like new.
