30 some years ago I worked a couple of years logging but I was only cutting fence posts compared to what you have in your photo but back then I bought a new stihl 034 made in the USA. Used it steady for two years logging and then kind of once in a while around the farm ever since. I can't believe that it still runs as great as ever. Over the years I think I only put a carb kit in it.
Few years ago I bought a new husky lawn mower because years ago their saws had a good rep. I'm guessing this lawn mower was made in China. What a peace of garbage.
Around here there really isn't any place to get anything fixed. People just buy something and then when it breaks in probably 13 months they throw it away and buy a new one.
