Ok ... I have read C-Speed's ignition timing help and I still have a question. The timing light gun is set to 0 ... I am on the third mark. It goes ...

mark (0TDC) .........................mark(14)/mark(16)/mark(I am on this one ... 18 deg.)

So if the gun is set to 0 and this is the case, when I dial the number up on the gun the marks run away(counter-clockwise). Is this right?

What the hell is the point of the other numbers on there if all you use is zero, or am I doing something wrong?
