The scale for TDC is underneath the pointer. My first message has a picture of it. It doesn't do any good to move my pointer because the scale is underneath the pointer. I think the best thing to do is paint a thin line at the outer edge for TDC then put the timing tape on because I don't see how the BTDC scale can be used. If you see the picture from the first message there's no nearby BTDC scale to use to set the static (idling) timing.
The attached picture shows the more accurate TDC mark. It's about 1.5 degrees to the right of the original TDC of '0'. Each dash is 2 degrees.
