Abstract
Abstract An ignition distributor wherein a drive plate is fixed to the distributor input shaft; a pair of centrifugal weights are pivotally connected to the drive plate and normally biased to the retard position: an advance plate is pivoted with respect to the distributor shaft with the pivoting movement controlled by the centrifugal movement of the weights, the advance plate being connected to the distributor cam which is fixed to the output shaft: a stop plate movable with respect to the advance plate is locatable in various positions with respect thereto, each position establishing a different maximum outward movement of the centrifugal weights.
