If your Echo Chainsaw engine cranks but doesn’t start, there could be several reasons. It could be due to no fuel at the carburetor or cylinder, a fuel mixture that is too rich, or no spark. Another reason for no spark could be incorrect gap. In this case you should adjust it to .65mm (0.026 in.), clean or replace the spark plug.
What to do if my Echo CS-400 engine cranks but won't start?
If your Echo Chainsaw engine cranks but struggles to start or doesn't start at all, several factors could be at play. A clogged fuel strainer or fuel line, or issues with the carburetor might be the cause; in such cases, cleaning or replacing the affected parts is recommended. Additionally, an overly rich fuel mixture can prevent the engine from starting, so opening the choke, cleaning or replacing the air filter, and adjusting the carburetor might help. Make sure the stop switch is in the ON position. Inspect the spark plug for proper gap, carbon buildup, or fuel fouling; adjust the gap to 0.65mm (0.026in.) or clean/replace the plug as necessary. For other carburetor, electrical, or interlock switch problems, consult your Echo dealer.
