Re: (brad black)
Brad, I'd be interested in seeing the diagram. I just did two of the Carby flywheels. They started at 4 lbs. on one of them I just removed the back "ring" and the outer circumference up to the "lump area, whacked off 17 oz. On the other I also turned a taper on the inside ring, out to the timing dots. removed 19.5 oz. I am just interested in what others have done.
