Dumping the FBO timing advance plate.

The 48 total. I assume that's just initial plus mechanical with no vacuum assist, right? If it likes it and doesn't spark knock, put the fire to it.

48 vac included.
It was 52.
I leave the distributor just loose enough where I can move it.
If needed I can pull over and take a little out of it.
