this question is for my enlightenment.

i just did my rails/cam replacement and used 4degree offset keys. so as i am looking down on the dampener the timing marks go from 0 right should be "before tdc" and left of 0 should be "after tdc".

if the dampener is rotating clockwise. i would describe your timing before top dead center(to the right of 0). when i added the 4 degree keys the manual shows by making the keys sit in one position (right or left) you advance or retard the 0 point. (in my case the addition of the offset keys brought the timing on the dampener back to about 2 deg after tdc.)

also as i analyze the rotation of the engine when a chain stretches the timing would be retarded therefore you should be reading after tdc.

now i might be miss reading this, my view is from in front of the engine looking in. i know right hand vs. left hand is from the pass compartment.

i'm just looking to clarify for my own piece of mind.
Thanks Much!
