Echo blower

middleforkNovember 15, 2012

I have an older Echo blower that I just put a carb kit into . It has a Walbro carb and sometimes I have to pull the choke out about 1/4 of the way to keep it running . Any ideas how I can cure this ? thanks

Try backing out the Low Speed adjustment screw on the carburetor about 1/8 to 1/4 of a turn. The L screw is the one on the carb closest to the engine and probably is marked L in the carb casting. It probably has an unconventional head. If you have one, try tapping a 22 gauge automotive type wire connector onto the head of the screw, allowing you to grip it to turn it.

Middlefork: You seem to have a lean fuel mixture conditon , have you ensured your fuel filter is unrestricted ? If clear and your carb circuits are clean then a simple tuning is warranted . Normally 1-1/4 to 1-1/2 out from seated will be optimium . Prior to tuning ensure your fuel tank is fresh and over half full also a new or clean air filter is require for best tuning results .

Hi ewalk .... Glad you are still here! It is evident that the blower carb is set too lean, no doubt. Those additional measures are good advice to eliminate any other problems. Keep up the good work!
