Purchased a 125b from Lowes in August of 2014. Out of the box it ran ok but would bog down. At first I found that keeping the fuel topped off would help the situation but after a while that wouldn't keep it from bogging down and eventually dying. Took it in for service spring of 2016. Had it cleaned/adjusted/refilled with fresh fuel. Worked ok for about a month and then started bogging down again. Took it in again, had it cleaned/adjusted/filled with fresh fuel. Again it worked fine for about a month then started doing the same thing. All the while I was meticulous in having clean, fresh fuel. I only made a gallon at a time, which meant that I would use it up in less than a month. The unit never sat more than a couple of days because I have a long drive that needed to have the pine needles blown off regularly.
I wont be taking this in for service again because when it died on me last week, I got so pissed off that I tossed with all my might into the street. I then brought a Dewalt 20v battery powered blower to complement my Dewalt battery trimmer.
I purchased the Husqvarna blower based on what I thought was the manufactures reputation for building high quality engines. Boy was I wrong. I will never buy another Husqvarna product.
