Locating dimple on timing gear

[Nosetime]

My first car was an MG midget, engine was apart in a couple milk crates...I got it together and running at 15 years old. I've owned and worked on lots of stuff over the years and when I came to the Model A a couple years ago, I remember laughing at the simplicity. Why finding TDC is a problem, I find amusing. I guess the point is, we all bring a different set of skills and experience to the table.
