It's Stihl number 1135 084 4100. It's suppposed to be for the preheat winter/summer shutter on a 390. The part I received looks nothing like what was originally on the saw but my dealer said they went to a new style and it's right?? Can I just run the saw without the shutter in place in the summer? The old one falls out from vibration every time.
