Why is my Echo CS-670 engine hard to start or not starting?
- CChristopher HowardJul 28, 2025
If your Echo Chainsaw engine is hard to start or doesn't start, several factors could be at play. First, check if the fuel filter or fuel line is clogged; if so, clean or replace them. If the fuel mixture is too rich, try opening the choke, cleaning/replacing the air filter, or adjusting the carburetor. Ensure the ignition switch is on and the spark plug isn't defective, covered with carbon, or fouled with fuel; clean, adjust the gap to 0.6 mm to 0.7 mm (0.024 to 0.028 in.), or replace it as needed. For carburetor or electrical problems, consult your ECHO dealer.
