I set the timing on my car once before but now that I need to do it again I cannot remember how it goes. Maybe I do know but I feel like I'm overthinking it and I'm just confusing myself. Its an 85 buick 231 v6 ccc controled can someone verify this. The timing mark has an arrow pointing at 10-12 mark, i set the mark from the pulley to match it. Make sure the rotor is pointing just before the #1 plug on cap. Unplug the 4 wire ccc plug from distributor. Turn car on and adjust the timing. Turn car off, tighten distributor again and plug it back in. Is that right?? I found a thread months ago about how to but I cannot find it anymore.
