I'm pulling an E85 burning 4 cylinder out of an old Edmonds midget racer. It has a Seco drive hub at the engine. There is the drive hub, engine plate, part of the bell housing, flex plate. It has a starter, but I don't think that matters. I split the ball flange, slid the ball tube back and see the U-joint. I was under the impression that the hub on the flywheel was splined, but i can get no movement. Anyone out there with any experience with these? I wish SJFast was still around.
