These Crane adjustable vacuum advance kits let you tailor your ignition to the advance you want. The adjustability provided by these kits permits you to run the maximum amount of ignition advance throughout the rpm range, without incurring detonation. Once they're installed, you can quickly compensate for changes in fuel quality and altitude. Each kit comes with a vacuum diaphragm, an Allen wrench, advance weight springs, and instructions.
