Hopfully this can help you with your problem. I bought the "128ld" trimmer and I had running issues for the first 3-4 tanks of gas then it run better than I expected.I ran it at 32-1 to make sure that my new unit had more than enough oil during the break-in period as I do to all of my products. it ran bad at first with the bogging issue as you discribed with no power after the 1st tank at 32-1 and 50-1 after that I had no problem and had great power from all of my products from husqvarna. I had a problem with the head and took it back to the store and traded it in and got a new one it did the same thing. These units must have to break in for a few tanks of fuel and they will work as expected if not better. I own everything husqvarna for my landscaping business needs and they are one of the best that I have used.
