Neil, what is the "over-heat" safety switch??? And is that in the Pertronix?
This intire discussion has got me to thinkin ( not necessarily a good thing
)and that is ~~ Could the engine box temp be a cause of excessive heat for those not running the blower full time? Just a thought. While looking at my engine the other day I took notice of my air into the box hose and it points toward the coil however the air flows over the end of the exhaust manifold at the hot section which is wrapped.
