I like the Huskqvarna 2-stroke whackers, blowers, and chain saws vs. Stihl, if for no other reason that I can't get them online or without a huge markup in price. I do run some SeaFoam through my equipment once a year and they are so old now I can't remember when I bought them. Interestingly, my Rancher chain saw has a larger engine (55 cc) than my first Honda motorcycle from 1970. I also rode a 2-stroke triple 750 Suzuki GT-750 in the '70s without issue, it had that nice automatic injector system so no mixing, and had to keep the radiator full, LOL.
