Thanks, Lads. Mitch, we bought the car just over a year ago with about 42,000 km on it. Fresh engine rebuild then by a highly respected engine builder in BC, Canada. No documentation on it really though other than it's a 2332 cc engine. We've now got 55,038 km on it and we drive a lot. I know that electronic ignition can last forever but I also know that it doesn't take much to make one fail and if they fail, it can be complete failure in the middle of nowhere likely without a quick source for replacement.
I've read with great interest the threads talking about spark scatter, mid range missing, many ignition problems were actually carb problems ( or was it the reverse ? ) etc. My engine has the Pertronix Flamethrower 2 system with an 009 dizzy and fuel via a couple of Weber 38's and it runs well throughout the range. My logic is to simply change out the old for the same new parts for a system that is known to run well while keeping the old parts on board as spares if the need arises. Not knowing any better I ordered the 7 mm wires that Pertronix sells too. What ever plugs are in there will get changed out too.
