Why Echo CS-501P Chainsaw engine starts hard or does not start?
- CChristopher LeJul 29, 2025
If your Echo Chainsaw engine is hard to start or doesn't start at all, several factors could be the cause. It might be due to an obstructed fuel strainer or fuel line, in which case you should clean or replace them, or consult your dealer. The carburetor may need attention, so it's best to see your dealer. A fuel mixture that's too rich could also be the culprit; try opening the choke, cleaning or replacing the air filter, adjusting the carburetor, or seeking assistance from your dealer. Ensure the stop switch is in the ON position, and if there's an electrical or interlock switch issue, consult your dealer. Finally, check the spark plug; if the gap is incorrect, it's covered with carbon, fouled with fuel, or defective, adjust the gap to 0.65mm (0.026 in.) or clean/replace the plug.
