I have ever figured out that goofy chart. I use a micrometer, measure the metering rod I’m using and find one that is a bit leaner. That’s how I do it. I’m not near smart enough to use the chart.
I use a digital calipers to measure the metering rods. I have found some from Edelbrock to be out of spec plus I cant read those fricking little numbers on the rods without a microscope.
