I am having trouble figuring out  how to use the muti  Keyway Crank Gear. I can see how it goes if stock original Timing is wanted. One Mark on Keyway and One on outer Edge of Gear. If I want to advance Timing I think by just 4 Degrees what are the reference Points I need? The Picture from Y-Block Book I am thinking shows the Keyway to use and the Tooth marked A4 is what. The Timing Mark to count Pins? Thanks.  

  

Who is the vendor (seller) of the timing kit?

Can you give PN?

I figured it out. For now I am leaving it in original Timing setup. I don't have Information on the Camshaft Timing Specs so for now I want to get it finished and running without wondering if I have set timing correctly. I can always revisit Timing if I want to try Interesting the Comments from couple of other Members regarding their Experience with advancing Timing.
