    Good question.  Some of those 40’s were downright scary with vibration.  Once upon a time, back in “The Day” I attempted to balance one.  Maybe I didn’t know what I was doing (true), but the result turned out as bad or worse than the original.  Go for it if you want, but I wasted my time.

    BTW, do you know the 1960 40hps had a problem with breaking crankshafts?  Obviously, they didn’t all break because thousands of them survived.
