Auto plugs, electronic ignition, and ....

[eric r]

What would be the caveat for running auto plugs on the original magnetos?
What is the latest opinion(s) concerning the P-mag, now E-mag?
I am also considering the dual plasma CDI...
...I am installing a starter, so I'll have a reasonable sized battery (still with the 8amp alt), and I really do not want to go the one elctronic, one magneto route.

Here is Marc Z's page that addresses the emag issue: http://www.cozybuilders.org/Emagair_Warning/

Here is Klaus's page on electronic ignition: http://www.lightspeedengineering.com/Technicalities/sport_aviation95.html

With dual electronic ignition, you will want to have a second power source.

Not sure about the automotive sparkplug.  I am comfortable running them on my electronic ignition.  Still running aircraft plugs on my mag.

I used Autolite 386 plugs with magnecor wires  in my Cassutt (with bendix mags)this year at Reno with great results! The nice
thing about the AL 386 plugs is you dont need adapters! they already come with an 18 mm thread!

Revmaster Aviation makes a nifty conversion kit to change the magneto harness over to use regular automotive plugs. See: http://www.revmasteraviation.com/products/auto_spark_plug_conversion_assembly/index.htm

The auto plugs I use also do not need adapters.  I use standard "racing" harness for my auto plugs going to the electronic ignition.
