U.S. 41cc Vibration Reduction
Could use some help guys!I recently purchased a near new U.S. 41cc that I am now breaking in. I am very pleased with its running, but I am trying to reduce vibration as much as possible. I checked the run-out on the prop hub, it is .006" total run-out. Apparently the threaded hole drilled through the hub .006" off-center. Is this enough to experience a vibration or is this insignificant?

Yes, I try to keep any prop hub deviation/runout to less than .001", though that is my personal goal and a bit tight.
Also, I just won't have the time to search for it, but there was a good set of posts about balancing engines and I have used the technique to obtain excellent results. Try a search in both this and the "Engine Conversion" forums. The engines like yours were quite often re-balanced by users back in the day...
