I would check the crank snout if the crank is new. Then would junk that balancer and buy a fluid damper in a heartbeat ! Fourth one over the yrs. and no problems ! My last one is from 440 source.
That (checking crank) should have already been done, and then maybe try the heat, grease etc, at least that's what I'd do if money were an issue, but if it just wont happen then "Sling It" !!:eek:
