How to Adjust the Carb on a Homelite Blower

Save

A Homelite blower is used to keep your sidewalks and drive clear from debris and allows you to blow leaves into a pile in your yard instead of using a backbreaking rake. The carburetor controls the mixture of fuel and oxygen going to the engine. Over time, the carburetor may become out of adjustment, causing your blower to lose power and run erratically. Adjusting the carburetor will fix the problem; in a few short steps and only a few minutes your blower will perform like new again.

Things You'll Need

  • Small flat-head screwdriver
  • Place the blower on a flat workbench. Locate the three adjustment screws found on the side of the carburetor, just below the air filter. There are two screws side by side. They are marked "H" for the full throttle adjustment and "L" for the low speed adjustment. Underneath the "H" and "L" screw is an idle screw marked "C."

  • Turn the "L" screw clockwise until the screw seats with the screwdriver. Turn the screw back counterclockwise one full turn. Start the engine and let idle for two minutes. Turn the "L" screw counterclockwise by 1/8 of a turn until the engine runs smoothly. Shut off the engine.

  • Turn the "H" screw clockwise until the screw seats. Turn the screw back out counterclockwise one full turn. Start the engine and advance the throttle to the full throttle position. Turn the "H" screw counterclockwise by 1/8 of a turn until the engine runs smoothly in the full throttle position.

  • Rev the engine. If the engine is sluggish to get to the full throttle position, turn the "C" idle screw clockwise 1/8 of a turn and rev the engine again. Repeat this step until the blower revs smoothly to the full throttle position.

Tips & Warnings

  • Do not over adjust the "H" screw; trying to get more power out of your blower by running the engine at a higher RPM will cause damage to the internal engine components.
