The first one: why my cam gear shows that advance is turning the gear counter-clockwise and retard turning it in clockwise, but other cam gears show the opposite:

What is the right direction to advance?
Another question: as you can see in my Sk2 installation, the difference between the Z6 setting and the Y8 one (down in the cam gear) is about 2 degrees, and its all know, that the real difference between the Z6 and Y8 is about 4.75 degrees, so: should I set the cam gear to the Y8 mark, or retard it by myself the 4.75 degrees needed?
Thanks.
