@Gordon Nichols posted:I agree with Stan. I’ve seen them used on a lot of VW and 356 engines and they tend to be sensitive to heat soak and premature failure. It’s ALWAYS best to carry a spare Pertronix module. You will use it eventually on an air-cooled engine.
So do I- another reason to work at getting underhood temps as close to ambient as possible. Feeding more air into the engine compartment than it actually needs will carry away latent heat radiating off the sheet metal (and engine itself), the engine will run cooler (cooler air entering the fan and carbs means the engine will be operating under proper parameters a larger percentage of the time) and the pertronix module (which should be better built to handle higher underhood temps but isn't) will last longer. If you look at it from the standpoint that it's not if but when the module will die and are prepared it won't be so much of a shock.
