The new Edelbrock Pumper Series carburetor is designed for today's high-performance four-stroke engines. The accelerator pump allows crisp throttle response and added external tuneability for applications that demand a broad power band. Edelbrock Pumper Series carburetors offer these benefits along with the superior features of the original Edelbrock carbs: 

• 440 Stailess Steel sealed ball bearings on the throttle shaft for smooth, precise throttle operation
• Carburetor is electroless nickel plated for superior corrosion resistance and durability
• Increase top-end speed and acceleration through a unique fuel metering system and high-flow flat-slide design
• Edelbrock carbs not only increase power but are less affected by altitude changes
• A simple, externally adjustable single fuel circuit design
• Top-end mixture calibrations are made by changing the needle... No Jets!
• Won't bog under extreme conditions, such as rough whoops and hard landings
• Adjustable accelerator pump provides instant throttle response and increased tuneability
• Pumper Series carbs have billet aluminum float bowls and are electroless nickel-plated for durability
• Internal fuel cell and anti-slosh plate ensures consistent fuel delivery and performance in extreme conditions

The Edelbrock R&D Team is hands-on, installing and testing Edelbrock carburetors on their stable of bikes and ATVs. This attention to detail is your assurance of top quality, accurate fit and maximum performance.

Actual horsepower, torque and air/fuel ratio numbers are obtained using the Edelbrock chassis dyno. This allows for highly accurate evaluations and precise fuel calibrations.
