Ok, thanks for the info. I found on the summit website harmonic balancer counterweights. The harmonic balancer that I would like to buy has a removable damper that I can change the counterweights. Summit does sell 50 oz counterweights.
Counterweights
I always thought that something that is supposed to balance something else would be symmetrical?
I still have time to think because I still can't get the harmonic balancer off. I broke the removal tool today. It was bending outward as I was turning the bolt.
