My LD128 had the symptoms, starts an runs at idle and low speeds. Give it full throttle, and it starts to speed up, then die.
Tried all the fixes:
I noticed when adjusting the new carb the engine would spit and backfire. First indication of a timing issue.
Replaced ignition module, now it runs like a champ.
This is the first time in years of working on small engines that a timing/ignition problem was the problem.
May need to have the unit checked. Could be something as simple as a clogged muffler, air filter, fuel filter or engine wear or damage.

Check the fuel lines for cracks/breaks. If they are o.k., then:
Youwillneed to disassemble the carburetor and spray with carb.cleaner.Makesure the small screen is free of debris. (Should be able to seedaylightthrough it.)
Use a Den Tek Brush, (http://www.drugstore.com/products/prod.asp?pid=165357&catid=1152),to clean the small portals in carb. These portals can become blocked. Reassemble and start.
If the carb. parts are more than 4 years old, you may have to replace them.
If you need further assistance on:
1. Fuel line replacement or
2. Carburetor kit replacement
Just let me know.

Probably needs a carb kit, check main jet and main fuel inlet jet, is the spark crisp, fat and powerful, try running it with a borrowed coil as this may have an intermittent fault. Is fuel cap breather working or blocked, these small carbs are very sensitive. Make sure all is well with gaskets and diagrahms. Good luck the Yeti

Could be clogged gas cap. Take the cap off and see if you can blow air through it. If no air passes, the trimmer will become vapor locked and wont be able to get enough gas.

Husqvarna is a good brand, if you are having trouble with running at full speed there is something inherently wrong with your unit you do not want to keep it around, it will lead to more problems in the future. I would recomend that you return it and purchase a Stihl they are very reliable if you want a machine that stands the test of time. Even a Weed-eater brand from Walmart will start better than the one you have right now and you will pay less or the same for a comparable unit, That will run great! Good Luck...
