Your going to make that adjustment with the O2 sensor connected and you are looking for a number around 40 on the 4 cylinder dwell scale. 35 would be richer and 45 would be leaner. Seeing as how the number tends to wiggle around a little I will set them just a tad on the rich side. That means when you look at it and it is bouncing around the 40 mark just make sure that it spends more of it's time bouncing under 40 rather than over.
