I had all the normal fuel problems with my chain saw, leaf blower, tiller and a few other gas powered things. Every shop told me the problem was with the fuel additives used by the refineries. Based on a couple of shop recommendations about three years ago I started using the Star Tron stuff.
Haven't had a single problem with anything since then.
