"well the starter pulls so much at them temps that the ignition just don't get the juice it needs)."

The thing you DON'T realize is due to forward voltage drop in the semiconductors in the Pertronix unit, you will actually have a WEAKER spark at a given battery voltage than with a quality set of breaker points in good condition!

My Papaw raised "baccer" (tobacco) and corn with the Super A, but the fondest memory was of the sawmill. He owned a small sawmill for sawing "baccer" sticks. The Super A was the powerplant. When I was old enough (7 or 8), I would get up early and be dressed to ... [Read Article]
