Most saws the dern muffler bolts loosen and wear the holes egg shape vibrating. I don't know why they changed from using springs to hold the mufflers . Engineering I guess. I've had to do many of the sthil and other broken bolts in engines of all kinds . It's always a gamble , I'd try the acid to eat the steel it may take awhile but it works. Cylinder kits for that saw run near $300. Might be more now. I haven't done any in a couple years.
