I really like most things about my Stihl MS261, but every once in awhile it ticks me off. The worst feature on it is the stupid complex "flippy caps" for gas and oil. The caps contain some kind of complex mechanism so they can be opened with a half turn. But every once in awhile, in spite of my best effort, the oil cap doesn't quite latch even by all appearances it is, and then as I pick up the saw and walk to where I'm going to cut, the cap comes off and dumps bar oil all over my leg. My saw is probably five years old, and I don't know if that's how they still do the caps, but I think a plain old screw off cap would be the hot setup.
