Edelbrock Performer Series Carburetor Calibration Kit

The Edelbrock Performer Series Carburetor Calibration Kit (also called a carb jet and metering rod kit or carburetor tuning kit) lets you fine-tune the air/fuel mixture on your Edelbrock Performer or Performer-based carburetor. Each kit is matched to specific Edelbrock carburetor models, so the components suit the carburetor it is made for.

Key Features:

• Includes metering jets in a range of sizes for adjusting the main fuel metering circuit
• Includes metering rods to tailor part-throttle mixture
• Includes step-up springs in several rates, so you can change the point where power enrichment begins
• Includes a metering rod retaining spring in applicable kits
• Sold as a kit, with the components and sizes chosen for the carburetor model it supports
• Made by Edelbrock, a long-established name in carburetors and performance parts

Matching the jet, metering rod and step-up spring to your engine, setup and altitude is a common way to cure a lean cruise or a rich stumble. Changing one variable at a time and road testing between steps makes the results easier to read. Select the kit that matches your carburetor part number.

Note: This part is intended for uncontrolled (non-emissions controlled) vehicles or vehicles used solely for closed-course competition.
