Herb Adams says a lot things.
That approximation might have some merit - if referring to a specific radius of rotation.
1 lb. off the center of the crank does nothing.
1 lb. off the pin at 3.31" stroke does something.
1 lb. off the OD of a 440 counterweight does a whole lot more.





totally! It was a approximation IMO, with No specifics to radius of rotation. As you state the further out, the better the effect. mike
