For once I have to say I don't like something on a Stihl, I HATE those stupid caps. I know the EPA is supposed to love them. I've broke one. I've not paid close attention closing them and had gas or oil running all over my leg more than once. What's even worse is you can't get old style caps to replace the damn things. In over thirty years of running Stihls I have yet to break, strip or lose a old style cap. They can be a ##### to get loose if you over torque them, but I guess I'm getting old, I can't stand the new ones. Having arthritis in the hands it is very hard for me to manipulate the little flippys, my son's like the things.
