Yes 33 degrees is a bit much. Try setting to 28. That far advanced may have been the cause of the first flame out being that engines will run hotter with that much advance. Getting hot can also warp things and make them leak. I would also still advise you to make sure the hub key is intact and the hub did not slip on the crank.
