Hey Les et al,Thanks for your thoughts. I'm under the impression that William Wayne'sCorvair engine conversion uses two ignition system wired to a single set ofplugs successfully. Does he use some kind of high-voltage isolation diodesor something to prevent the two systems from interfering with each other?Or maybe the two ignition systems don't care about each other. Would amagneto and a conventional battery system be okay to use together in thisconfiguration? Maybe some of you Corvair guys could weigh in on thisplease. About the 'fouled plug'. I'll just have to take my chances with that. I ammore concerned about a catastrophic failure of a single magneto system thanabout loosing one plug out of four. I am hoping that a prudent maintenanceschedule will fend off the 'fouled plug' scenario.You are correct about my 'former starter position' statement. My error.(The 'ol brain just ain't what it used to be.) I meant to say that I haveseen magneto adapters/mounts that position the magneto under the exhaustmanifold, next to the aft cylinder on the port side of the engine (as theengine sits in a Piet). I have an after-market oil filter kit mountedthere. This prevents me from putting a magneto in that area. So, I wasasking if there is another way to mount a second ignition system other thanputting it there or putting it in the distributor hole where it is exposedto the prop blast?LarryNX1929A---
