At the risk of opening a can of worms, can anyone describe or point me to a step by step tuning procedure? I started with the factory manual but the 500 RPM idle setting through me off right away. 700-800 seemed smoothest and gave me the highest vacuum. I'm guessing the process needs to be adjusted for a 48 year old engine. My car is 63 Polara 500 383 4 barrel (Carter AFB) with 82,000 miles. No points; someone replaced it with a Pertronix at some point before me. I just changed all the plugs, which to me all look to be a little wet-fouled in the same way. I was missing 3 cylinders before changing the plugs; it's running much smoother now and I don't think I'm missing any. I have a vacuum gauge, timing light and tach. Mechanically, I'd classify myself as competent but not proficient. I don't have nearly the experience as many of you. The Internet says 100 different things and confuses me. I guess what I'm looking for is a general top down procedure; which comes first, timing, idle mixture, etc. What should I check first? What am I looking for with the timing light? What's the best way to make use of the vacuum gauge and when? I got previous links to the vacuum gauge diagrams from some of you. Cool and helpful, but I'm not sure of the order of operations and priorities. As always, thanks. - Jim Jim Altemose, Long Island, NY '63 Polara 500 (Max Wedge) '63 Polara 500 (383) '65 Belvedere I (Street Wedge) '71 Bronco -- -- Please address private mail -- mail of interest to only one person -- directly to that person.
