Why does my Echo CS-3410 Chainsaw engine start hard?

If your Echo Chainsaw engine starts hard or not at all, it could be due to several reasons. The fuel strainer or fuel line might be obstructed, requiring cleaning or replacement. The fuel mixture may be too rich; in this case, open the choke, clean or replace the air filter, or have the carburetor adjusted or serviced. Also, check the spark plug for proper gap, carbon buildup, fuel fouling, or defects. Adjust the gap to 0.65mm (0.026 in.) or clean/replace the plug as needed.
