What to do if my Echo CS-490 engine cranks but won't start?
- BBrandon OchoaJul 27, 2025
If your Echo Chainsaw engine cranks but doesn't start, consider these potential causes and solutions: * **No fuel at the carburetor:** Clean or replace the necessary components. * **Fuel at the cylinder:** Consult your Echo dealer for assistance. * **Muffler wet with fuel:** Open the choke, clean or replace the air filter, adjust the carburetor, or consult your Echo dealer. * **No spark at the end of the plug wire:** Turn the switch on or consult your Echo dealer. * **No spark at the plug:** Adjust the gap to 0.6 to 0.7 mm, clean or replace the plug, or replace the plug entirely.
