It's a common issue. Caused by the exhaust warming up the mechanism side of the handle. Stihl seem unable/unwilling/struggling? To sort the issue (maybe the 661 was the fix, which didn't turn out perfect!)

 

I saw a post about greasing the mechanism an thought before I make an ugly looking piece of metal to make the handle stiff, I'll have a go at that

 

This is what I was greeted with. Lots of dirt and debris that would increase the effort needed to get the mechanism to work.

So, after much cleaning and liberal amounts of grease to the moving parts. I'm left with a very easy to operate chain break. Noticeably different from before. Time will tell if its a good fix. Should have got some pictures of it clean. The amount of black crud that came out was unreal.

 

This may affect some and not others. I'll get some more pictures to show what ive done and will update in the future on how well the fix has worked, if it did.

 

 

 

This is what I've done on mine cleaned de greased and re greased hopefully it works better tomorrow

It is a big improvement. I managed to get a go of mine the other week and after ringing up with a 25" bar it worked fine. All crisp and comes on well. Doing it once every few months would be fine to keep it in good order needs doing on all my saws tbh

Did mine, was surprised how clean it was. Big improvement, was milli g the end of last week and it worked a treat every time.
