Scientists at a leading research institution have achieved a groundbreaking feat by altering the fundamental properties of ...

Ignition timing is typically split into three types. The first is initial timing—that is, the amount of spark lead that is set using a timing light (aimed at the harmonic balancer) with the engine at ...

This GM HEI has the typical gummed-up mechanical-advance mechanism. Note the corrosion on the advance-weight pivot pins (arrows) caused by voltage arc-over and lack of lubrication. Brad Urban at The ...
