"The fan turns clockwise(if my memory serves me), so I would assume that turning the distributor clockwise would retard ignition.
When adjusting the ignition timing, disregard what the fan is doing (other than keeping our tie out of it) as the only correlation is that the dist. shaft. will rotate ccw or cw. Depending on your year, the distributor rotation is different. Thus, advance the timing by rotating the dist. opposite rotor direction (engine speed increases). To be most accurate, use a timing light and the timing marks.
