Why does my Echo SRM-2620 start hard or not start?

  If your Echo Engine starts hard or doesn't start at all, there are several potential causes. The fuel strainer or fuel line might be obstructed, requiring cleaning or replacement. The fuel mixture could be too rich, in which case you should open the choke, clean or replace the air filter, or adjust the carburetor. Ensure the STOP switch is in the ON position and check for electrical problems or issues with the interlock switch. Finally, inspect the spark plug for incorrect gap, carbon buildup, fuel fouling, or defects; adjust the gap to 0.65mm (0.026 in.) or clean/replace the plug.

  If your Echo Engine runs but dies or doesn't accelerate properly, the air filter might be dirty and needs cleaning or replacement. Another possibility is a dirty fuel filter, which requires filter replacement or fuel replacement. Also, the fuel vent could be plugged, which needs to be cleaned or replaced.
