So when you say max advance of 10-12 if im reading you right my initial timing should be between 22-26? Or are you saying initial should be 10-12 and total 32-34 before 3k?

I just want to make I'm reading you right.

20 - 22 initial and 10-12* mechanical advance. Total being 32-34* depending on your plug heat range, fuel, and of course how the plugs look after a wot run.
