Hi guys, I received the NovaRossi 29050/K flywheel kit for my Nova .21 on road engine. The fit is fine on the engine but the threads on the nut/shaft are not 1/4x28 for the hex coupler as advertised. It looks to be 6mm?? I don't see a flex coupler that is 6mm for a .187 flex shaft. I thought Octura makes one but it looks like it is for an electric motor. Any suggestions? Thanks in advance.
