Man of $tihl

I don't know. I measured the pin last night and it's definitely 12mm. Maybe he had it in the wrong box? Regardless, I don't believe MS 440 cylinders came without a decomp. None that I've seen anyway. I paid $144 for the kit last week. I have to say, I think I stated I could get them for around that price, at least around the same price as the AM cylinders being pushed. Believe I proved just that.
I owned a original ms 440 that didn't have a decomp. Also it had a Stihl cylinder.
