[Mgs] valve adjustment

[Paul Hunt]

It shouldn't need to be as accurate as that.  The base circle *should* exist 
for a minimum of 180 degrees at the heel, and probably slightly more than 
that.  Which means that anywhere in that 180 degrees *should* give the same, 
maximum clearance.  But as individual cams will show, the greatest clearance 
can exist over a much smaller rotational angle than that, and in any 
position.  It's that you need to find, on your cam, and adjust to.
