I bought a Husky 326R brushcutter, lightly used, and it is a piece of crap. It doesn't accelerate, it is not well balanced, and the trigger assembly basically fell apart. Suposedly this is one of their "high end" models, and it barely runs. I am not impressed. It is nt half the machine my 15 year old Echo SRM-2400 is, and it has these stupid bike handlebars to boot.
I am surprised that the initial repair was so expensive. $300 will almost buy a new machine. I would have likely gone that route, but hindsight is better than foresight............
It makes sense to me that the knucklehead "tech" blasted that sucka off with an impact and shocked the crank. I would write letters to the editor, tell anyone who will listen, and keep it up as long as I could. Those asp holes hosed you, and their lack of support will bite them someday in lost business, which seems your only recourse.
Of course, Stihl makes a mighty fine product, in my experience.......
All the Huskies I have seen may be fast, but look to be stapled together like Japanese Zero airplanes.
