Thanks a lot guys.  I will order new screws to make sure. Looking at the screws, the thread is coarse but looks coarser than M5 0.8?  I have the original screws.  Strange set up, Tapping a hole in alloy with a screw. Does the swarf just sit in there till you take the muffler off next time? Do you use alloy lube as you screw in and cut the thread?

Well screws went in a treat and I just backed off when they felt really tight and screwed clockwise again, till they bottomed. I just dipped screws in meths.  Gave it a run this morning and all well so far.  It is a 40mm piston and barrel kit and original was around 38mm. Seems to be what Stihl are supply for FS 300 now.  Thanks to all!

Should you ever need to remove the screws always turn the screws anti clockwise when re fitting until you feel them drop into the thread, if you just whack them in they will start to make a new thread and tear the alloy out destroying the thread.

Good shout....you should feel it starting to 'skip' in the top of the thread when gently turned anti clockwise....then gently turn it WITH YOUR FINGERS clockwise. You will get a 'feel' for the thread. Once started to pick the thread up correctly, then use a lightweight narrow bladed screwdriver to wind it in. As said before....it should be lightly seated. Dont get it seated then give a quarter turn more just for good luck
