Carb Tuning
Edelbrock has developed calibration charts for each of its carbs that map out the rod and jet changes required to go richer or leaner. The base calibration is at the center of the chart. Moving up and to the right richens the calibration; moving down and left leans the carb. To use the chart, decide how many stages you want to go, then cross-reference the number in the nearest circle to the chart to find out what jet and rod combo you need. These charts are printed in the owner's manual, available free from Edelbrock, for each carb along with a list of jet and rod part numbers. View Related Article
