Pulled a real bonehead move and ran about half a tank of straight gas through my Stihl saw. I thought when I was pouring it that it looked light, finished cutting and loaded up. Got home and found my saw gas, marked MIX in big black letters, sitting right next to where I store my saw. Think I did any damage? Should be the only time I ran straight gas in it, and I definitely plan on draining the gas asap.
