So I chose to tweak as best I can, put up with the noise and see if the new setting of gears and such find their way to happiness over time. I also found that one of the blades was a little loose. Upon assembly I noticed an added noise. one of the blade rivets was not fully set and I was afraid to try wacking anything too much for fear of breakage. Plus, one side of the rivet had been whacked to almost nothing already. I put a small piece of paper in the gap between the blade shaft and the blade to stop it from moving as a test. The added noise went away. So now, with a dab of JB weld in a few strategic places I expect that bit of noise to be gone. I JB'd all the other blades in a similar way for balance and prevention. Just a dab mind you.
