Muffler on a 2-stroke Stihl Blower

[theoldwizard1]

I have a several year old Stihl handheld 2 stroke blower that still runs great ! However, the muffler screws (Torx, socket head) come lose about every second or third time I use it. Yes, it only take a minute to tighten them but I don't want to strip/wear out the threads in the cylinder.

Suggestions ?

Loctite is only good to 300F. I would think that the cylinder gets hotter than that.

Worth a try !

try a conventional split lockwasher or even a star washer.

There's always safety wire

Can't be safety wired. The Torx screw is at the bottom of a deep well in the muffler.

I've used red locktite on any and all exhaust that I do. Clean screws and holes with brake cleaner. Use red locktite. Let it sit. Should work if not jb lockweld

Stihl saws use a serrated washer for lock washer duties. Might try to find some of those.
