You mean The ones that dont give you a positive lock versus false lock and dump a tank of oil or fuel randomly after several minutes of use. Yeah that happened twice. I double check my 361 everytime now. My 660 still has the screw in caps and i prefer itSpeaking of the Stihl saws, The only feature I don't like is those 1/4 turn fuel and oil caps.
The 1/4 turn caps on my 362C-M have a positive lock. They work well and I prefer them to screw on caps, especially the ones that require a t-wrench to get them tight enough to seal (I'm talking to you Echo).
Now the choke on my new FS240 on the other hand.... it's a knob that's both recessed AND has a spring loaded collar that you have to depress in order to operate it. It's impossible with gloves on. Stihl generally does ergonomics as well or better than their competition but this one's a fail.
