Manifold Vacuum Advance what am I not getting?

I pulled my number one plug to look at it but honestly, I have almost no time on this motor as it is this may be 20 minutes of tuning and driving around about 7 miles. I don’t trust you yet for high uses. I’m having some brake issues and I’m working through.

Too much timing and the plug looks pretty hot.

You can use that type of plug. It doesn’t have that dark black coating on it.

Those are better to read.
