CW or CCW, that is why the Lucas distributor should have a little arrow pointing to the left or to the right. If you install a CW Lucas distributor in a CCW engine, the scroll seal oilers will reject the oil back down and soon your dist will burn up its bushings from lack of oil; also, the mechanical advance mechanism will not advance anything. Find a Lucas distributor catalog and you can hunt for British cars with "backwards" distributor rotation which will equal opposite engine rotation (from normal) as the catalog will list distributor rotation direction for each one. The MG XPAG engine (and distributor) runs "backwards".

I thought the direction of rotation depended upon which side of the equator you reside on.

I'm unsure as to your statement that the XPAG engine runs "backwards". The direction of rotation is indeed clockwise as is the B Series.

Mine is quite still. But I and the rest of the universe spin around it in a counter-clockwise direction. It is dizzying at times.

I am very disappointed none of the experts here figured the rest of the simple equation. It is more than CW or CCW for the dist, you also must know which side of the engine the dist is on to figure engine rotation. I guess sometimes the most simple of things slip past the great experts here.
