I had the same problem although I didn't bust the flywheel [also SFI approved].
I'm not going to repost again, but just look at your original thread, and my post [Mike U], and install a push start button.
Also, someone pointed out the depth, I checked mine as per the Powermaster instructions, and everything was perfect, but the starter still showed its ass when starting.
Now I just push the start BUTTON, and wait a sec until the starter is at full spin, then turn the ignition key to the "ON" position, and the engine fires right up with no after noise from the starter.
