Tuning

You don’t need an 02 sensor. They help but it’s not a mandatory item. If you elect to get an 02 sensor, AEM has good stuff.

A dial back timing light is just that. It has a dial that you twist to adjust the light. So when you want 10-15 or 20 degrees advance on the inital timing and a standard light flashes, where does the timing mark go? The dial back will see it when you twist the dial to 20*’s.
That's awesome, I need to get me one of those. I'm thinking that this is going to be a very good learning curve for me and enjoyable at the same time. Hope to be in contact with the owner of the duster real soon. I have a friend going with me to help look the car over as he's had more experience with engines than me and also hopefully to bring the car home. I haven't talked about it to much because I don't want to jinx myself like I did in the past.
