It seems to me that a sharp chain will put more pressure on a saw than a dull one. Since it is cutting the wood and the other dull chain is just running on top of the wood. The worst thing I have seen with a dull chain is the excessive wood dust it produces. I have seen saws with dull chains, and take the air filter off and finding a block of dust on it. That may be were people are getting scoring from when running a dull chain. Especially if the filter is old and poor condition. This is my thought.
