This sticky fuel can clog up the carburetor and cause the engine to stall. Clean the dust, dirt, or debris by using compressed air, soft bristle brush, and carburetor cleaner solvent for easy and quick cleaning. Sometimes the impeller nut is a lock nut, but other times the nut is secured with Loctite. Old fuel sitting in your ECHO leaf blower can leave a gummy sticky deposit behind that restricts fuel flow.
Note: During installation, ensure that the throttle plate is facing the engine, and the choke plate is facing away from the engine. Replace with a new primer bulb. Remove the filter cover, air filter, retainer and foam pre-filter; wipe away any dirt from inside the cover.
A clogged carburetor is most commonly caused by leaving fuel in the leaf blower for a long period of time. The function of the muffler is to decrease engine noise from your leaf blower. The impeller is essentially a fan blade that draws air into the blower housing and forces it out the blower tube. In this case, your blower may be on the incorrect setting, which can prevent it from blowing air.
