I got out and did a little testing today. I ran both the stock and ported MS180s with .043 and .050 guage chain. The PS-401 has .050 chain. I found it interesting that I got the fastest times on both the stock and ported 180s with the 0.050 chain. I was not expecting that. The 180 cuts best with a moderate amount of pressure. Not real light, but not pushing much either. The Dolmar was another story. It doesn't have the RPMs of the 180 but has a larger engine and more torque. It cuts best when you really lean on it and pull the RPMs down.
I'm just curious as to how many tanks of fuel you have through the 401 now?
