Right now total is 29 degrees measured with a dial back light. In the past few weeks I have been working under the assumption there was to much mech advance. So I installed a mech advance timing limiter plate. Which does what its intended to do, but did not help my problem. So at this point I have it in the 16 degree slot. My initial is set at 12 degrees add the the 16 mech and you get 29 degrees so its right on I guess. My intention is to move the plate to the 18 degrees slot or remove all together when I replace the springs. I recently set the initial using the vacuum gauge method and the motor likes 14 degrees but trying to limit the overall timing has me setting it at 12 initial.





Ill take a look, but I don't think I have a leak. Runs to good and idles steady and smooth on the vacuum gauge. No ping at high rpms. What do use to check for vacuum leaks ? Carb cleaner?

This is a plot of my curve against some factory curves I found while researching. Mine is the green line in middle.
