FAQ: Ignition System

3. Is it possible to reassemble a distributor's mechanical advance mechanism in reverse order? I have a later model (1974) Atomic 4. - Top

It is indeed possible to install the flyweights in a Delco distributor upside down. In this configuration, the ignition will retard rather than advance. To be sure the advance mechanism is installed correctly, rotate the rotor against the spring return. You should only be able to rotate the distributor in a clockwise direction (for a slight amount into the spring tension). If you can rotate it in a counterclockwise direction, the flyweights are in backwards. - Updated: April 15, 2004
