My trimmers sat for awhile. I cleaned the fuel tanks, installed new gas lines and primer bulbs. They will run but will not take any throttle.

Hi Mike,

When old fuel sits in a carburetor it will create varnish on the insides of the carb. The varnish plugs the small openings inside the carburetor. You could try removing the carb and cleaning it. I full rebuild is difficult as Ryobi does not offer any parts for the carburetor. You might also consider simply replacing the carb. It is part #308054013 and is available from http://www.ereplacementparts.com .

Good luck with your repair!
