I've had this Sachs Dolmar KMS-4 for about 25+ years. It did not have a bar/chain when I got it, so the first bar was a 24" Windsor sprocket tip. Recently I downsized it to a 20" Oregon PowerMatch Bar with 73LGX chain. With both of those combos, it has plenty of power even when the whole bar is deep in the cut. I've always used Amsoil Synthetic 2-stroke oil and premium fuel in it. It doesn't get used much in Florida now, but Irma clean-up pressed it back into service. Ran great still and got the job done! Time to clean it up and put it back on the bench until the next storm!
