Now you're saying my mechanical advance is SET at 28 (crank) degrees. Also blatantly untrue. The only thing 'SET' is the total amount of mechanical advance. It is variable up to 28 crankshaft degrees. That's why it's called an advance curve. I had my choice of 10, 12 or 14 magneto degree curves. On advice from the speed shop owner in '75 I chose 14.

Vertex Model OAC
Model OAC is available for 4,6& 8 cylinder engines and can be supplied with or without a tach drive and with or without automatic advance.

You are right! You have me all jacked up on how I interpited what you were saying. So I now understand that you have 28 at idle and the type mag you run has an additional mechanical advance of some value.
If you put a timing light on it your timing is @ 28 degrees at 900 rpm.
What is it when you are at 3200 rpm?

If you feel the need to compare everything you know about my mag against everything I know, start a new topic please.
