Ahem, ahem!!..............Well, it may be a SMALL subset, but personally I wouldn't have anything else. My first saw (new) was a 621 in around 1981 I would say, soon acquired others the same. They have needed few repairs in 39 years, mind you I'm a Farmer, I'm not trying to clear cut forests ! Perhaps ten years ago I happened on a Stihl 026, ( supposed to be the bees knees), I always felt it was rather inadequate. Two days ago, I thought I'd run it against one of my recently refurbished (courtesy advice cantdog) 49sp's (This one free, from a skip.). In green ash 16in dia, the 49sp roared its way through time after time, while the 026 was positively outclassed, and felt anaemic and in every way a disappointment, and yes, it's throttle is opening fully and it's well up together. It might as well have been battery electric.
I have other saws, but if I want to walk to the job, start the saw and do the job, I will take a 49sp every time.
Mind you, I like to run them, work them, keep myself warm from them AND have them to look at.
If I could figure out how, I would post a photo of my little band....All strong reliable runners.
So....wonder no longer, I am here !
The man behind the counter in 1981 ish, told me, and I remember it well......"If you look after that saw, it'll last your lifetime!" (mind you, he knew I'd been out drinking with his son the night before...). Well, it looks like it might, and if someone else eventually does the same, I don't doubt that it'll do the same for them.
