I turned it up because someone on here told me that a ported 372 would run its best set at 13800 or below. My 2171 will hold almost that in the cut.
I don't worry about a melt down on that saw, it will still for stroke a little at 16000. I ran it at that rpm for many years. Years ago my son was cutting firewood with that saw. He was about 1/2 mile from my house. I heard the saw screaming after about 4 hours, I jumped in my truck and drove as fast as I could to stop him. It was turning over 17000 for who knows how many hours. I turned it back down to about 15000, he was pissed at me and told me it was to slow.
