Edelbrock carburetor tuning explained from the basics through fine adjustments: fuel pressure, float level, idle mixture screws, metering rods, jets, step-up springs, and the accelerator pump. Learn what each adjustment changes, how to diagnose rich and lean symptoms, and what to check before swapping parts. Includes wideband readings, fuel and ignition considerations, altitude, and spark-plug condition. CHAPTERS
