> I think we're going to have to agree to disagree on this one. I ran a Bristol 400 for
10 years with an entirely conventional ignition system - lovely car but, unless everything was on top line with the ignition system, it was prone to misfiring.

When I purchased a 405 30(!) years ago it was fitted with a Mobelec electonic system which, whilst this overcame the misfiring problem, was not entirely reliable. Moreover, when I started classic car rallying such a system would clearly be frowned on by the rally scrutineers as non-original. So back to the conventional coil/CB system. But, once again, unless everything in the ignition system was A1, the occasional misfiring was possible. However, 8 years ago, on fitting a high energy coil with a ceramic ballast resistor - end of problems; never a misfire, reduced wear/pitting of the contact breaker points, absolutely no arcing at rotor arm. I set the plug gaps at ."025; cold starting is always excellent.

Each to his own, I suppose.
