I have a little over 20 hrs on the '95 and it still works like it did when I installed it. I have the engine apart too offen to tell on the AF with chain saw valve.

What model chain saw are these decompressors off?

The ones that I use are for a Stihl 650 660...I think. I went to the saw shop and told him I needed a decompression valve for a Stihl and that is what I got. I have sence bought the cheaper blue ones off e-bay. They work just the same. I buy most of them from this guy....

Great stuff, thanks.
What thread pitch and diameter are they?
I've been looking on Google and I spotted a patent for a different type of compression release that goes in the sparkplug hole and the plug goes through it, Unfortunately I can't see the picture properly to fully understand it. I'll see if I can sign up to it.
This is the plug one...
