Why won't my Echo Blower start?

  If your Echo Blower won't start, there could be several reasons: * There's no fuel reaching the carburetor, in which case you should clean or replace it. * The muffler is wet with fuel, so you should open the choke. * The fuel mixture is too rich, so you should clean or replace the air filter. * There is no spark, so turn the switch to ON. * The spark plug is defective, covered with carbon, or fouled with fuel; in these cases, clean, replace the plug, or adjust to 0.65mm (0.026in.).

  If your Echo Blower's engine starts but then dies or doesn't accelerate correctly, consider these possibilities: * The air filter is dirty, so clean or replace it. * The fuel filter is dirty, so replace it. * The fuel vent is plugged, so clean or replace it. * The spark plug is dirty or worn, so clean and adjust or replace it. * The cooling system is dirty or plugged, so clean it. * The spark arrestor screen is plugged, so replace it. * There is improper adjustment, so adjust it.
