Yeah buddy, they are fast, and not bad for torque if done right. The mmws 2166 I got off you had some nice grunt but wasn't real fast, same with the 2166 I'm running now, little timing advance would probably fix that . This one is strong saw but also fast. Running a round chain, I have videos of it cutting slightly quicker with a square chain in the same wood, but it isn't frozen lol. It's a great work saw . I think I have an eight pin on it here Mike.
