The air hammer is the go in my opinion because there's a lot less chance of damaging the Flywheel and it's very quick, but the way Joe suggested in the beginning got me out of a spot and is always a good backup.
Have a happy new year and I'm going to have a nice cold beer tonight and cheer it to all on outdoor king. Thankyou all very much ,oh and by the way I'm not doing anymore mowers till next year.
