Help With Removing the Flywheel (Rotor)

Hello: My 1987 Yamaha 25SH has no spark. I am trying to remove the flywheel (which Yamaha calls the rotor) to help diagnose why there is no spark. Do I need to remove anything other than the 24mm top nut to pull off the flywheel? I am using a 3 arm gear puller and I have put a lot of torque on the gear puller without budging the flywheel. Are there any other bolts or anything else that need to be removed to free the flywheel? Please see the pictures, attached. Thank you in advance.

Take all the bolts out then get another pulley the type that has 3 bolt threads and screw them in where those 3 shinny bolts are in your last picture . you have the wrong type of pulley . This flywheel is the same flywheel used on the EH models and its the tapper lock type.
