Mopar Performance Distributor adjustable advance?

You guys make me want to cry. Why? Because people assume that everyone understands what they are talking about. I am not an electrical engineer, or distributor guru, or carburetor airbleed tip in guru either. I have FBO parts in 2 cars, one is running fine with them. The other one isn't together yet, but has the FBO distributor and module. All came recommended from a respected engine builder that occasionally makes comments on this site. Sometimes I feel like I am back in the Army, and my poncho fell apart on a forced march and now I am on the side doing push-ups for embarrassment, so that it doesn't happen again! I have no idea what those red gauges do yet, I have a set, they came with the new distributor. Just haven't gotten that far. Maybe Red Green can help me with some duct tape! I will keep watching, we're all in this together.

Any time you need help with this stuff, the call is free, LOL
