8BA timing

[40cpe]

I did the test through the spark plug hole and it verified my TDC mark. This crank pulley has a pronounced dot near the TDC mark. I hope you can make it out on the picture. It has the holes for the crank mounted fan like a '40, and it came to me in my '40. So I set the original mark with the head off by bolting a bar across the cylinder. I've checked it using a tie wrap through the spark plug hole. And it is reasonably close to a factory dot on the pulley. I'm pretty certain the TDC mark is correct.
