Thank you for contacting Husqvarna's Answer Army.
The throttle on the two-stroke engines is advanced to a "high idle" position when the choke is engaged; it will run at that higher speed until the throttle is depressed and the high idle linkage is released.
As you indicate the engine will not accelerate properly when the throttle is fully depressed, it is possible only a carburetor adjustment is needed to add more fuel to the Low Speed fuel circuit in the carburetor.
However, if the engine continues to run too fast after throttle activation releases the high idle linkage, that may indicate some other condition exists with the carburetor or fuel flow circuits, or possibly with the engine.
Either way, we would suggest you get the unit to an authorized service dealer for evaluation of the fuel system, including the carburetor, and also the complete engine.
