Engine runs but only half throttle

I have a 123 Husqvarna trimmer that will crank and run, but when you give it full throttle it only increases about half speed. I have removed the carb. and cleaned it out with carb spray. It still does the same. The adjustment screws have a post that keeps them from turning only a half a round.Any suggestions will be appreciated.

Check the throttle cable to make sure it hasn't gotten out of adjustment and not opening the throttle all the way. Have a nice day. Geo

If I'm correct, those posts are removable, they're there so after the carb is set, it can't be leaned or richened enough to damage the engine. But if everything checks out on the throttle/carb end then possibly remove the muffler to see if the port or spark arrester in the muffler is plugged.
