In the timing section of "Power Tuning" we learned why a distributor has an ignition curve and how it works. Now we're going to look at the procedure for setting up an ignition curve or modifying an ...

A battery in a traditional car cannot directly create engine spark. It’s only rated at 12 volts, after all, so it needs a little help boosting the signal to the spark plugs. To make that happen, a car ...

Paging through an ignition catalog reveals all sorts of different ignition coils for conventional distributor-type ignition systems. To say it's a mite confusing is an understatement!Just how does an ...

In a perfect world there would be no need for ignition advance curves. As soon as the piston in your vintage Vette reached top dead center and the engine built maximum compression, you'd be able to ...

The demands for better emissions and fuel economy in the mid 1970s necessitated leaner fuel mixtures. These leaner mixtures required greater voltage and more spark to ignite. This challenge led GM ...

Just like spark plugs, ignition coils can wear down and become faulty over time. There are many common signs that an ignition coil is getting bad, but one obvious sign is an engine misfire, typically ...
