[Purdy Swoft]

When the points are replaced , the points cam and upper breaker plate must be removed and replaced . Any time that the points cam is removed and replaced . The points cam must be replaced , pointing in the same EXACT position or the timing will change , that is if the timing was exactly correct in the first place . Points gap effects timing . More gap advances less gap retards .Ford specs for points gap was anywhere from eighteen to twenty two thousands as necessary . The spark happens when the points begin to open . When the rotor tip points at the number one contact in the distributor cap with NO counter clockwise backlash . The points should be adjusted to be just ready to open . That is why the specs for gap can vary .
