Mostly trying to find a way to keep the valves in the heads before the engi ne tried to kill me again! The standard Subaru ignitor chips are hopelessly feeble..In fact I seem to remember comparing the measured primary coil resistance and comparing it to the subaru Brat specs for the Subaru coil. if memory serves, it was about half of what the sooby spec was. What this means is two things.. 1) In the steady state condition (like you turn the ignition on and then st arted the engine) the ignitor chip is switching somewhere close to twice th e current it was designed for..Needless to say this puts a LOT more stress on the ignitor chip. 2) If the IC107 works then I bet there are hundreds of coils out there that could be made to work in the same application.. This is why it is important to get off the Sooby ignitor chips ASAP if you haven't done so already. When I sold the plane some 3 or 4 years back it wa s running dual GM ignitor chips (with a third spare mounted on the same pla te that I could swap to if one died on a X country trip). Those things are bullet proof..i even took an old one and shorted it out..This would instant ly kill a $300 Sooby ignitor chip, the GM worked perfectly after said abuse .. Good luck all..I hope your still enjoying your airplanes..I have fond memor ies of mine. Frank 601HDS (about 500 hours when sold) RV7a..Also about 500 hours but about twice the distance..a lot of it in IMC ...:) _____ From: owner-stratus-list-server@matronics.com [mailto:owner-stratus-list-se rver@matronics.com] On Behalf Of Don Walker Sent: Tuesday, June 08, 2010 3:22 PM Subject: Re: Stratus-List: Spare parts source Mine have been rusty forever...here in the humid country of East Texas. I h eard that the rust on the coils is not a big deal. Maybe you can educate me on this a little more. don Thanks for the info on the spares. _____ From: Larry McFarland ronics.com> Sent: Tue, June 8, 2010 11:38:07 AM Subject: Stratus-List: Spare parts source mailto:larry@macsmachine.com>> Hi guys, For you who fly behind the Stratus Subaru or just do dual ignition on one o f the varieties, I've been revisiting my engine wiring and found my ignition coil plates are rusty from the moist air coming thru the cowl. Having spares has real meri t because spare parts are often discontinued after 10 years or so. Ignition coils purchased nearly 8years ago for $35.00 each are now $93.00. Useful a lternatives to the pricey Echlin IC107 coils can be found by searching for coils used on a 1987-1990 Mitsubishi wagon or van. The equivalent parts are easier to find at $30.00 and up. I chose O'Rielly's Auto Parts on line and they have 4 sources for this coil. I've maintained a spares box for all th ings consumable, brake pads, bungees, fuel lines, scat tube etc, and after only 157 hours of flight, I guess coils are next. Fly safe guys, -%20-%20-%20-%20-%20-%20-%20-Matt%20Dr======= ======
