Sell it and buy a good one. twocents I had a brand new BHJ once. It slipped the outer ring over an inch around after one trip to the track on a 500 hp engine. Sent it back and had it repaired, but they offered no explanation on the cause of failure and wouldn't return my phone calls.
Been using ATI and Fluidampers ever since.
