I just read the tech archives and see this:

"Although not discussed in MP's instructions, the mechanical advance is a Mallory adjustable YH type (same as used in most Mallory distributors). It is fully adjustable from zero (locked out) to 28 degrees. We set them at 28 degrees when we ship them to MP. All you need to adjust (or lock out) the advance is a Torx driver to loosen two button head screws. "

How do I know if mine is adjustable? Also where do these torx screws reside?

**EDIT**
I think I got this figured out. If my distributor has this, I will need a set of the keys to set the gaps between those tabs.

So do most people with performance STREET motors run vacuum advance or leave it disconnected?
