My timing marks have been painted over so I can barely see them....I can see several marks with smaller marks in between them...and on one side it looks like it says ATC and on the other side of the marks is say BTC...which I assume to mean after top center and before top center.....
I was going to set it as 10 degrees Before TC while at idle....but I don't know which mark that would be....
Can someone send me a pic of their timing marks? Or give me a diagram of what they mean.
Thanks
