Waste of time...Take the starter out okay. Get something that you trust not to slip between the teeth on the flywheel and have someone hold it thats not a pussy. get a 3/4 inch drive breaker bar and put you 17 mm on that thing. If you can't muster up the strength to get if off, get a hollow pipe and put it on the breaker bar handle like a glove. That should do it very quickly.
