Which clutch did You put on your engine? I have an ABI (Adrien Bertin Influenced) with Serpent clutch for my 720. The package said it's a conversion kit for Serpent, put it did not fit to the Serpent clutch, I think it had packaging problem
But that is a different problem.
Now I saw Teemu was driving an NT1 with Orion engine, but I don't see any conversion kit for the NT1.
Please let me know how You have put yours together.
