Can’t make out 502 mpi timing marks.
 
Anyone have a picture of a new balancer so I can see what the marks are. I can’t make these out.

Look for timing tab basically off of timing cover.

I think the little white mark, and the scratched off paint, represents 8 degrees. I think I can see a zero at the next mark past it, indicating 10. I added some markings to your pic to show you what I think I'm seeing.

that deep groove is tdc use an advancing timing light

And the line scribed in closer to the bottom, that is not as deep, is done at merc for timing at full advance. It would mark 32* in most cases.
