Help me tune my dizzy?

The dizzy is one of those white box, Chinese, "Ready to Run" units. I have know idea how much mech advance is built into it or at what rpm it comes in. I intend on figuring that out my next day off though.
I recently pulled one of those apart and adjusted the mechanical advance in it. Unfortunately, no vac adjustment.
