FAQ

This carburetor is designed to fit Echo chainsaw models CS-300, CS-301, CS-305, CS-306, CS-340, CS-341, CS-345, CS-346, CS-3000, CS-3400, and CS-3450.
This unit replaces Walbro WT-589, WT-589-1, WT-589A, and WT-402. It also directly replaces Echo OEM part numbers A021000231, A021000232, A021000230, A021000760, and A021000761.
Common signs include the engine failing to start, idling roughly, stalling under load, or experiencing inconsistent power delivery. If you have already cleaned the existing carburetor and replaced the fuel filter and lines without improvement, the internal diaphragms or needle valve are likely worn out and require replacement.
Before installation, ensure your fuel lines are clear and not cracked, as old, brittle lines are a frequent cause of air leaks. It is also highly recommended to replace the intake gaskets (OEM V103000021) to ensure a proper airtight seal against the engine block, which is critical for consistent engine performance.
Replacing the carburetor is a straightforward task that typically takes 30 to 60 minutes. You will need basic hand tools, including a screwdriver set and a socket wrench. Take care to note the routing of the fuel lines and the placement of the throttle linkage before removing the old unit to ensure a smooth reinstallation.
The most common cause of failure is the use of ethanol-blended fuels, which can leave behind gummy deposits and cause the internal rubber diaphragms to harden or deteriorate during periods of storage. Keeping the fuel system clean and using fresh, stabilized fuel is the best way to extend the life of your new carburetor.
