Scag sthm engine eating oil

Yes it has that "smart spark module" just seems weird that it ran (for lack of a better term) before repairing the valve and now this. Going to pull the flywheel to make sure the key didn't share and screwed the timing up. Everyone I talk to says it sounds like a timing issue. What else can I do to correct this.

Pulled the flywheel and the key was sheared. Replaced the key, put it back together and she started up. But now the other head is dumping oil into the muffler. Blowing massive amount of blue smoke. Oil was actually dripping from the bolt that the exhaust bolts to the head.....FML! I'm assuming the rings are shot.
