Genuine Echo Carburetor A021003942 | PB-770 PB-770T PB-770H Backpack Blower OEM
Is your Echo PB-770 bogging down, surging at idle, or failing to hit those high RPMs needed to move heavy piles of leaves? The PB-770 is a high-performance machine that requires precise fuel metering. This Genuine OEM Echo Carburetor (A021003942) is the factory-authorized replacement designed to restore "first-pull" starting and the full-throttle force your blower was built for.
This part is the most current version and replaces older part numbers A021001870, A021003940, and A021003941. Don't risk your 63.3cc engine with "universal" aftermarket carburetors that run too lean and can cause permanent piston scoring. Stick with the genuine part factory-calibrated by Echo.
Full Throttle Performance: Specifically jetted for the PB-770 series to ensure the engine reaches peak RPMs for maximum air volume (CFM).
Factory-Set Calibration: Ready to bolt on and run. The idle and high-speed circuits are preset to meet Echo's strict emissions and power standards.
Ethanol-Resistant Components: Features high-grade diaphragms and seals designed to withstand modern pump gas (E10) better than generic alternatives.
Smooth Acceleration: Eliminates the "flat spots" or hesitation when pulling the trigger, providing crisp power delivery across the entire throttle range.
Direct Bolt-On Fit: Every linkage and fuel line nipple is a perfect 1:1 match for your PB-770T or PB-770H.

🛠️ Blower Pro-Tip: A surging engine is often a sign of an air leak or a clogged fuel system. Installation Tip: When replacing the carburetor, always inspect your Fuel Lines and the Intake Gasket. If the lines are stiff or cracked, they must be replaced to prevent air bubbles from leaning out the engine. Maintenance Tip: To prevent future clogs, always use a fuel stabilizer and never store your blower with fuel in the tank for more than 30 days.
