A carb rebuild usually works miracles with trimmers. The jets are usually not adjustable enough because they have limiters installed over them. If it is over 2 years old I would get a carb kit. You should also check the fuel lines because it is also a common source of failure.

Your trimmer has a carburettor which has both slow run and fast run jets - clearly the slow run one is blocked or out of adjustment. The carb will need to be stripped and cleaned using carb cleaner and compressed air but carefully does it as they are quite complex. If the carb has two adjustable jet needles, set them both at one full turn out.
