stihl 044 dp muffler help

[newoldschool2]

well I finally got around to putting a duel port muffler on my 044. everything was tight when I left the shop. I made some cuts and when I took a break for fuel/ touch up the chain I noticed that one of my screws that hold on the spark arrester screen had vibrated out. I have circled them in red in the photo below. after that I was done for the day, could not find that little bugger anywhere with the magnet.

So what does everyone do to correct this problem or is it something that you have to live with and constantly tighten the screws?

Loctite

Preferably Locktite 272

I wouldn’t be scared of red locktite on that. Blue will give a little more with the heat than red will.

On those screws I have had good luck putting a star edged washer under them and then setting them hard.
