Echo a021003971 Carburetor WYK-387

Product Description

The ECHO a021003971 is a WYK-387 series carburetor designed as a direct OEM replacement for compatible ECHO outdoor power equipment. The carburetor meters and atomizes fuel for delivery to the engine, controlling the air-to-fuel mixture required for reliable starting and steady operation under load.

This carburetor is suited for ECHO handheld and walk-behind outdoor power equipment applications where the WYK-387 carburetor is specified. Typical install scenarios include carb rebuilds or full replacements during seasonal service, post-storage restoration, or troubleshooting hard-start and lean-run conditions. Installation should be performed by a qualified technician familiar with small engine fuel systems.
