Stihl MS 441 muffler bolts

[redunshee]

muffler bolts came loose and are lost. Don’t recall the correct size to replace them. My IPL is home and I’m out of State. Assume they are a T 25 or T 27. Anyone know what size and length?

Thanks. Probably 1/2" in length should work.

This time make sure they are torqued down. I've never heard of four coming loose at once. Sounds a bit goofy. Possible sabotage? Just curious.

No. I didn’t use a thread locker. Only lost the two that attach the muffler to the cylinder.

Maybe that is what the little hole plugs are for,
to keep you from losing the screws when they come loose......
