Why my Echo CS-370F Chainsaw engine cranks but starts hard or doesn’t start?

If your Echo Chainsaw engine cranks but struggles to start or doesn't start at all, several issues could be the cause. The fuel strainer or fuel line might be clogged, in which case you should clean or replace them. The carburetor itself may have a problem, and it is best to consult your Echo dealer for assistance. If the fuel mixture is too rich, try opening the choke, cleaning or replacing the air filter, or adjusting the carburetor. A lack of spark could also be the culprit; ensure the switch is turned to the ON position. Finally, check the spark plug: if the spark gap is incorrect, adjust it to 0.65mm (0.026 in.); if it's covered with carbon or fouled with fuel, clean or replace it; and if the plug is defective, replace it.
